match: do not weirdly include explicit files excluded by -X option

Actually, this was the original behavior. Before a83a7d27911e, "log" and
"files" showed nothing if "FILE -X FILE" was specified, whereas "debugwalk"
got confused by an explicit FILE pattern. Under the hood, "log" and "files"
use m() and ctx.matches(m) respectively, and "debugwalk" uses ctx.walk(m).
I suspect dirstate.walk() goes wrong in _walkexplicit(), which seems to
blindly trust m.files().

I reckon the original "log"/"files" behavior is correct, and drop the hack
from the differencematcher.

# Dummy extension that adds a delay after acquiring a lock.
