perf/core: Fix PERF_RECORD_MMAP2 prot/flags for anonymous memory
commit 0b3589be9b98994ce3d5aeca52445d1f5627c4ba upstream.
Andres reported that MMAP2 records for anonymous memory always have
their protection field 0.
Turns out, someone daft put the prot/flags generation code in the file
branch, leaving them unset for anonymous memory.
