The fake "less" script was not being made executable. This can cause the
tests that follow to fail. This failure is not apparent on platforms which
have DEFAULT_PAGER set to the string "less", since lib-pager.sh will have
set the $less variable to "less" and the SIMPLEPAGER prerequisite will have
been set, and so the "less" script will have already been created properly
and made executable in test 2 'git grep -O'. On platforms which set
DEFAULT_PAGER to something like "more", no such script will have been
previously created, and tests 7 and 8 will fail.
So, add a call to chmod to make the fake "less" script executable.
