fsmonitor: add support for extra `hg debuginstall` data

This might make some things easier to debug, and for default bug
report templates it'll help collect more data from users all at
once. I don't actually need fsmonitor in our bug reports (we don't use
it), but this demonstrates the utility of the preceding patches
without having to add new things to core.

Differential Revision: https://phab.mercurial-scm.org/D6682

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
