Subject: [PATCH] perf python: Add missing util/rlimit.c file to the python binding linkage list

In commit c4a852635edd ("perf data: Increase RLIMIT_NOFILE limit when open
too many files in perf_data__create_dir()") we started using the
evsel__increase_rlimit() function from util/rlimit.c used
in the python binding, which caused this entry in 'perf test' to fail:

  $ ./perf test python
   19: 'import perf' in python                                         : FAILED!

After:

  $ ./perf test -v python
  Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
   19: 'import perf' in python                                         :
  --- start ---
  test child forked, pid 1100249
  python usage test: "echo "import sys ; sys.path.insert(0, 'python'); import perf" | '/usr/bin/python3' "
  test child finished with 0
  ---- end ----
  'import perf' in python: Ok
