[PATCH] get_maintainer: Append parenthesis back to trimmed subsystem name

[Kai-Heng Feng]

When a closing parenthesis gets trimmed, there can be unmatched
parenthesis in the subsystem name. This doesn't play well with
git-send-email:
(cc-cmd) Adding cc: intel-gfx@xxxxxxxxxxxxxxxxxxxxx (open list:INTEL DRM DRIVERS (excluding Poulsbo, Moorestow...) from: 'scripts/get_maintainer.pl'
Unmatched () '(open list:INTEL DRM DRIVERS (excluding Poulsbo, Moorestow...)' '' at /usr/lib/git-core/git-send-email line 554.
error: unable to extract a valid address from: intel-gfx@xxxxxxxxxxxxxxxxxxxxx (open list:INTEL DRM DRIVERS (excluding Poulsbo, Moorestow...)

So append parenthesis back if it was trimmed to make git-send-email
work again:
(cc-cmd) Adding cc: intel-gfx@xxxxxxxxxxxxxxxxxxxxx (open list:INTEL DRM DRIVERS (excluding Poulsbo, Mooresto...)) from: 'scripts/get_maintainer.pl'
