ENHACEMENT: warn about potential patch apply errors when package version requested don't match recipe

User can specify package version with --requirements option:
`p4a apk --requirements=python3,pillow==7.1`
Then p4a will download specified version instead of the one defined in the Pillow recipe. This recipe has patches to apply, and p4a will fail trying to do so because patch almost always strictly requires the exact input files of the particular package version - the package version which is specified in the recipe itself:
```
self.handle_command_exit_code(exit_code)
File "/home/u1/.local/share/pipx/venvs/python-for-android/lib64/python3.11/site-packages/sh.py", line 821, in handle_command_exit_code
raise exc
sh.ErrorReturnCode_1:

Suggestion: warn user clearly that the package version he requested does not match the recipe version, and the patch is likely to fail.

Commencez au point d’entrée `p4a apk --requirements` et suivez la manière dont la version demandée d’un paquet est comparée à la version de la recette Pillow avant l’application de `setup.py.patch`. Reproduisez l’incompatibilité avec `pillow==7.1`, puis vérifiez que la commande avertit clairement les utilisateurs lorsqu’un patch de recette peut échouer parce que la version demandée diffère.
