file: add PACKAGECONFIG for auto options

A few options of file configure are set to auto, which can lead to
unpredictable effects when something in the sysroot does provide
things that satisfy the autotools checks.
In the worst case this will lead to package-qa failures as libraries are
not set in RDEPENDS but configured for the tool.

To mitigate changes of accidental configure set explicit options via
newly introduced PACKAGECONFIG variables for bzip, lzma and zlib
support, where the default is just zlib, as it was before
