[compiler-rt] [compiler-rt][memprof] Do not add libdl to MEMPROF_UNITTEST_LINK_LIBRARIES (PR #98221)

[Alexander Shaposhnikov via llvm-commits]

https://github.com/alexander-shaposhnikov created https://github.com/llvm/llvm-project/pull/98221

The memprof tests do not actually depend on libdl. 
They might have a transitive dependency on libdl through the runtime, but the runtime takes care of itself.
Based on the offline discussions it looks like this piece of code in cmake is a historical artifact.

Test plan: ninja check-all
