[compiler-rt] Fix musl build
The change in PR #154268 introduced a dependency on the `__GLIBC_PREREQ`
macro, which is not defined in musl libc. This caused the build to fail
in environments using musl.
This patch fixes the build by including
`sanitizer_common/sanitizer_glibc_version.h`. This header provides a
fallback definition for `__GLIBC_PREREQ` when LLVM is built against
non-glibc C libraries, resolving the compilation error.
