[PATCH] t4014-format-patch: do not assume 'test' is available as non-builtin

From: Johannes Sixt <redacted>

One test case used 'xargs test', which assumes that 'test' is available
as external program. At least on MinGW it is not.

Moreover, 'git format-patch' was invoked in a pipeline, but not as the
last command. Rewrite the test case to catch breakage in 'git format-patch'
as well.
