arm: Fix some testsuite fallout from r11-8168 [PR100067]

Commit r11-8168 changed the word ordering of a warning in order to
make the text more consistent.  Unfortunately, it neglected to update
some filters in the testsuite that are intended to strip such warnings
when we try to partially override the user-supplied command-line
options.

This patch rectifies this and also fixes some patterns that were
incorrectly specified in the first place.
