[exim-dev] testsuite permissions

I have my umask set to 0002, so when I do the git checkout, the
test/aux-fixed/* files are mode 0664 instead of 0644. Mode 664 causes
test 4 of script 15 to fail, changing it to 644 allows it to pass.
Should the runtest check the mode of one or more of those script files
to verify it has the group write bit removed since we know it's going
to cause a failure?
