[PATCH] t7510: do not fail when gpg warns about insecure memory

["Kyle J. McKay" <mackyle@gmail.com>]

Depending on how gpg was built, it may issue the following
message to stderr when run:

  Warning: using insecure memory!

Unfortunately when running the test, that message gets
collected in the stdout result of git show -s --show-signature
but is collected in the stderr result of git verify-commit -v
causing both the stdout and stderr result comparisions to fail.

Since checking for secure memory use by gpg is not the point of
this test, filter out such messages to allow the test to pass
even when gpg is "using insecure memory".
