Subject: [PATCH] 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
gcc version 7.3.1 20180712 (Red Hat 7.3.1-17) (GCC)
   8    13.87 centos:stream                 : FAIL egrep: warning: egrep is obsolescent; using grep -E
