[PATCH v6 12/14] t5520: replace $(cat ...) comparison with test_cmp

From

Message-ID
<67ea3f0238845f3717e85593e0f10c086df04280.1573595985.git.liu.denton@gmail.com>
In-Reply-To
<cover.1573595985.git.liu.denton@gmail.com>

We currently have many instances of `test <line> = $(cat <file>)` and `test $(cat <file>) = <line>`. In the case where this fails, it will be difficult for a developer to debug since the output will be masked. Replace these instances with invocations of test_cmp().

This change was done with the following GNU sed expressions:
	s/\(\s*\)test \([^=]*\)= "$(cat \([^)]*\))"/\1echo \2>expect \&\&\n\1test_cmp expect \3/
	s/\(\s*\)test "$(cat \([^)]*\))" = \([^&]*\)\( &&\)\?$/\1echo \3 >expect \&\&\n\1test_cmp expect \2\4/

A future patch will clean up situations where we have multiple duplicate statements within a test case. This is done to keep this patch purely mechanical.
