There's no need for shell libraries to have the executable bit. They're
meant to be sourced, and running them stand-alone is pointless. Let's
reduce any possible confusion by making it more clear they're not meant
to be run this way.

Log graph comparision logic is duplicated many times in:
- t3430-rebase-merges.sh
- t4202-log.sh
- t4214-log-graph-octopus.sh
- t4215-log-skewed-merges.sh
Consolidate the core of the comparision and sanitization logic in
lib-log-graph, and use it to replace the existing tests.
While at it, lose the singular/plural transition magic from the
sanitize_output helper, which was necessary around 7f814632 ("Use
correct grammar in diffstat summary line", 2012-02-01), that has
long outlived its usefulness.
