cli-tests: account for protojson whitespace randomization

Annoyingly, for JSON formatting protojson randomly selects a spacing
method (one space or two spaces) depending on a hash of some sections of
the Go binary, to discourage depending on its output being stable.  This
breaks some checks in the CLI tests of the contents of fscrypt.conf and
the output of 'fscrypt status'.  As there doesn't appear to be a
straightforward alternative currently, for now just update the tests to
take into consideration the possible extra space.
