tests: use grep -E instead of obsolescent egrep

Testing on Fedora 38 failed with:
  egrep: warning: egrep is obsolescent; using grep -E

The warning comes from
https://git.savannah.gnu.org/cgit/grep.git/commit/?id=a9515624709865d480e3142fd959bccd1c9372d1
. For further anecdotal evidence of the change, see
https://www.phoronix.com/news/GNU-Grep-3.8-Stop-egrep-fgrep .

This reverses the code check that goes back to e7d3b509af8b. grep -E is POSIX,
but there is a risk that it doesn't work the same on all platforms - especially
older Unix versions. It should however always be possible to put a GNU grep in
$PATH before running the tests.
