relocatable python: Be more permissive with mime type checking
relocatable python: Be more permissive with mime type checking

Fedora28 python magic used to return a x-sharedlib mime type for .so files.
Fedora29 changed that to x-pie-executable, so the libraries are no longer
relocated.

Let's be more permissive and relocate everything that starts with application/.

Fixes #4396
