Subject: [PATCH 1/2] ktest.pl: Always warn on build warnings

If a warning happens at build, give a warning at the end:

  Build time:   1 minute 40 seconds
  Install time: 17 seconds
  Reboot time:  25 seconds

  *** WARNING found in build: 1 ***

  *******************************************
  *******************************************
  KTEST RESULT: TEST 1 SUCCESS!!!!   **
  *******************************************
  *******************************************

This way, even if the test isn't made to fail on warnings during the
build, a message is still displayed that warnings were found.

Subject: [PATCH 2/2] ktest.pl: Avoid false positives with grub2 skip regex

Some distros have grub2 config files with the lines

    if [ x"${feature_menuentry_id}" = xy ]; then
      menuentry_id_option="--id"
    else
      menuentry_id_option=""
    fi

which match the skip regex defined for grub2 in get_grub_index():

    $skip = '^\s*menuentry';

These false positives cause the grub number to be higher than it
should be, and the wrong kernel can end up booting.

Grub documents the menuentry command with whitespace between it and the
title, so make the skip regex reflect this.
