typing: explicitly set the return type of `_InnerRevLog.raw_text()`

Somewhere between cd72a88c5599 and 2fd44b3dcc33, pytype changed the return type
from `Tuple[_T1, Any, bool]` to `Any`.  Both are wrong.  `mdiff.patches()` is an
alias for `mpatch.patches()`, which is selected via module policy (and breaks
the ability to infer the types).  However, `cext`, `cffi`, and `pure`
implementations all agree it returns bytes.

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