Subject: [PATCH] TagsCheck: handle license exception in first item of a
 grouping

The change in 7d707f7f (TagsCheck: handle license exception in grouping,
2023-03-03) is insufficient when the exception is on the first item in a
grouping, e.g.:

    License: (Apache-2.0 WITH LLVM-exception OR NCSA) AND BSD-3-Clause

Adjust `license_exception_regex` to exclude a leading '(' as well as a
trailing ')'.
