Remove redundant assignments to the "regflags" variable. There are no
code paths that have previously set the regflags to anything, and
certainly not to `|= REG_EXTENDED`.
This code gave the impression that it had to reset its environment,
but it doesn't. This dates back to the initial introduction of
git-grep in commit 5010cb5fcc ("built-in "git grep"", 2006-04-30).
