Had to also bump ubuntu version 18.04->20.04,
as was getting errors running the self-compiled pyinstaller otherwise (weird...):
```
from .utils.git import get_repo_revision
ModuleNotFoundError: No module named 'PyInstaller.utils'
```
(similar to https://github.com/pyinstaller/pyinstaller/issues/4403 )

Note re appimage: when trying to compile python 3.8.x on ubuntu 16.04, I am getting:
./Modules/posixmodule.c: In function ‘os_copy_file_range_impl’:
./Modules/posixmodule.c:10351:15: error: implicit declaration of function ‘copy_file_range’ [-Werror=implicit-function-declaration]
ret = copy_file_range(src, p_offset_src, dst, p_offset_dst, count, flags);
This is because ubuntu 16.04 has too old glibc.
The "setup" Windows binary we distribute allows users to "install" Electrum
on their system. The distributable is created by NSIS. During
installation a bunch of files will get unpacked in %programfiles(x86)%/Electrum,
including an "inner" exe that will be the entrypoint for the user to start
the application. A shortcut is also created for the inner exe.
With this change, there will now be two inner EXEs. One the same as before,
the other with a "-debug" suffix in its name. The debug exe is built as a
"console" application (as opposed to a "windowed" application), so when
launched via double-click a black console window would appear; and also
importantly stdin/stdout are handled properly for it (unlike for "windowed"
programs). (see #2592)
There will not be a shortcut or similar for the debug exe; it would just
be there as a debugging option we can instruct users to use when needed.
In particular early crashes during startup are hard to debug without
stdout/stderr. (see e.g. #6601)
- our new key now supports both
- note that we don't bother to "dual sign" for both sha1 and sha2, as
Win7 upwards sha2 is supported (and we already don't support XP, Vista, etc anymore)
If there is a collision between a branch name and a commit hash, git
will choose the branch, even if the full 40-hex-long commit hash is
given. GitHub disallows branches/tags with such a name but git itself
does not. By adding the `^{commit}` syntax sugar after a ref name,
we can tell git that we want the commit hash to be preferred,
and hence we don't need to trust GitHub (only git).

All (incl indirect) dependencies are already listed in deterministic-build/requirements*.txt.
This option makes it easier to manually rm a dependency from that list for e.g. testing.
This suppresses the pip script location warnings, like we already
do for AppImage. It also disables the Wine debugging messages by
setting WINEDEBUG=-all.
