A comment in 'ci/lib.sh' claims that the "OS X build installs the
latest available versions" of P4 and Git-LFS, but since
f2f47150
("ci: don't update Homebrew", 2019-07-03) that's no longer the case,
as it will install the versions which were recorded in the image's
Homebrew database when the image was created.
Update this comment accordingly.
