[compiler-rt] [DIAG][msan] fix libc check string for dladdr1 call (PR #69359)

[Lei Huang via llvm-commits]

https://github.com/lei137 created https://github.com/llvm/llvm-project/pull/69359

The check for dladdr1 for shared libc is too strict. Depending on how the system is setup we sometimes pick up the none generic lib name with the version string in it.

Update check to for libc to account for version string.
