package/llvm-project/compiler-rt: add libxcrypt dependency

When glibc was bumped to version 2.39 in commit
b5680f53d60acf8ff6010082f873438a39bd5d97 it removed the deprecated
libcrypt support.

But compiler-rt package still use crypt.h header and crypt() function
in the sanitizer code.

Use libxcrypt unconditionally since compiler-rt itself already depends
on glibc based toolchain.
