Subject: [PATCH 1/2] libkmod-file: gracefully handle errors from zlib
zlib won't necessarily set the system errno, and this is particularly
evident on corrupted data (which results in a double free). Use zlib's
gzerror to detect the failure, returning a generic EINVAL when zlib
doesn't provide us with an errno.

Subject: [PATCH 2/2] depmod: report failures in loading symbols
Previously, depmod would relegate failures of kmod_module_get_symbols()
to debug output, assuming the "error" was simply a lack of symbols.
Leave the ENOENT return to debug output, but report anything else as a
real error.
