[compiler-rt] Remove 'memprof_meminfoblock.h' from MEMPROF_HEADERS (NFC) (#95334)

Commit 8306968 deleted file
`compiler-rt/lib/memprof/memprof_meminfoblock.h`, but didn't remove it
from MEMPROF_HEADERS in `compiler-rt/lib/memprof/CMakeLists.txt`.

Remove unneeded leftover line in
`compiler-rt/lib/memprof/CMakeLists.txt`.

p.s.
GH #54777 reported a llvm14 build failure due to the existence of the
leftover line, but I'm unable to reproduce the build failure with llvm19
trunk.
