android build: rm blacklist.txt

this looks like broken dead code

- the "if" body is never entered as `.buildozer/` gets created by `contrib/android/build.sh`
    8eb3c43603/contrib/android/build.sh (L32)
- `blacklist.txt` is at `contrib/android/blacklist.txt` but the Makefile expects it at the root
    ref https://gitlab.com/fdroid/fdroiddata/-/merge_requests/24948#note_2643399062
- `blacklist.txt` is not referenced anywhere else
