KVM: selftests: Guard execinfo.h inclusion for non-glibc builds
The backtrace() function and execinfo.h are GNU extensions available
in glibc but not in non-glibc C libraries such as musl. Building KVM
selftests with musl-gcc fails with:
lib/assert.c:9:10: fatal error: execinfo.h: No such file or directory
Fix this by guarding the inclusion of execinfo.h and the stack dumping
logic under #ifdef __GLIBC__. For non-glibc builds, provide a local
stub for test_dump_stack().
