app-arch/xz-utils: workaround USE=pgo build failure
Workaround a build failure with USE=pgo by disabling instrumentation of the
crc{32,64} IFUNC resolvers.
No revbump as it shouldn't affect runtime at all - instrumentation would kill
it immediately if at all, it's not an issue from the profiled binaries, just
the instrumentation to profile them.
Bug: https://gcc.gnu.org/PR114115
Closes: https://bugs.gentoo.org/925415
