Subject: [PATCH next 2/3] perf tests make: Remove the last egrep call, use
 'grep -E' instead

One last case, caught while testing with amazonlinux:2, centos:stream,
etc:

   4     7.28 amazonlinux:2                 : FAIL egrep: warning: egrep is obsolescent; using grep -E
   8    13.87 centos:stream                 : FAIL egrep: warning: egrep is obsolescent; using grep -E
