t5312: drop "verbose" helper
t5312 has several uses of the "verbose" helper, as described in
8ad1652418 (t5304: use helper to report failure of "test foo = bar",
2014-10-10). Back then the "-x" trace option for tests was new, and was
not as pleasant to use (e.g., some tests failed under "-x", we did not
support BASH_XTRACEFD, etc).
These days it is clear that "-x" is the preferred way to get extra
output, and we don't need to mark up individual tests. Let's get rid of
the uses of "verbose" here, as one step toward eradicating it totally.
