The function pointer casts silence the compiler and allow the code to
build (and even run in the typical case). However, when building with
control flow integrity checks, the runtime (rightfully) complains about
calling a function via a mismatched function pointer type.
In order to make xdgmime properly relocatable so that unit tests can use
it without it reading and modifying the user’s actual xdgmime files, and
without the need to call setenv() (and get tied up with thread safety
problems), add a xdg_mime_set_dirs() method to allow the dirs to be
overridden. They will still default to the values of $XDG_DATA_HOME and
$XDG_DATA_DIRS.

Currently, all mime types are considered subclasses of
application/octet-stream, but according to the freedesktop
standard, everything but the inode/* types is a subclass of
application/octet-stream.
Update the special case for application/octet-stream so that all
types but inode/* will match with it and add unit test for it.

This commit factors out a function for comparing string suffixes, and at
the same time makes it safe for mime types that are shorter than the
"/*" suffix.
