tests: fix stat mocking with Fedora rawhide
GLibC has a really complicated way of dealing with the 'stat' function
historically, which means our mocks in turn have to look at four
different possible functions to replace, stat, stat64, __xstat,
__xstat64.
In Fedora 33 and earlier:
- libvirt.so links to __xstat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat and __xstat
In Fedora 34 rawhide:
- libvirt.so links to stat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat
Historically we only looked at the exported symbols from libc.so to
decide which to mock.
In F34 though we must not consider __xstat / __xstat64 though because
they only existance for binary compatibility. Newly built binaries
won't reference them.
Thus we must introduce a header file check into our logic for deciding
which symbol to mock. We must ignore the __xstat / __xstat64 symbols
if they don't appear in the sys/stat.h header, even if they appear
in libc.so

# Kludge for yajl include path on non-Linux
#
# As of 2.1.0, upstream yajl.pc has -I${includedir}/yajl among
# its Cflags, which is clearly wrong. This does not affect Linux
# because ${includedir} is already part of the default include path,
# but on other platforms that's not the case and the result is that
# <yajl/yajl.h> can't be located, causing the build to fail.
#
# Since upstream development for yajl has stopped years ago, there's
# little hope of this issue getting fixed by a new upstream release.
# Some non-Linux operating systems such as FreeBSD have elected to
# carry a small downstream patch, but in the case of Homebrew on
# macOS this approach has been rejected[1] and so we're left with no
# choice but to work around the issue ourselves.
