[PATCH 6/8] t1901: use tr in git repo structure output instead of expected value

[Lucas Seiki Oshiro <lucasseikioshiro@gmail.com>]

The test 'keyvalue and nul format', as it description says, test both
keyvalue and nul format. These formats are similar, differing only in
their field separator (= in the former, LF in the latter) and their
record separator (LF in the former, NUL in the latter). This way, both
formats can be tested using the same expected output and only replacing
the separators in one of the output formats.

Adjust the output of `git repo structure --format=nul` in t1901, matching the
--format=keyvalue ones. Compare this output against the same value expected
from --format=keyvalue.
