perf: fix perfrevlogrevisions --reverse

Currently, 'endrev' equals `len(revlog)`, a revision that does not exist.

When asking for the reverse order, the arguments passed to xrange are
`xrange(len(revlog), startrev)` which then crash.

We need to offset 'endrev' by one so we don't crash anymore. Also, we offset
'startrev' to ensure we get the same number of revisions with and without the
`--reverse` option.

# Blacklist for a full testsuite run with fsmonitor enabled.
# Used by fsmonitor-run-tests.
# The following tests all fail because they either use extensions that conflict
# with fsmonitor, use subrepositories, or don't anticipate the extra file in
# the .hg directory that fsmonitor adds.

#### fixing these seems redundant, because these don't focus on
