Subject: xlocate: add ability to pass certain flags to git grep

implemented what I thought would be useful and made sense, namely:

- `-E, --extended-regexp`
- `-F, --fixed-strings`
- `-G, --basic-regexp`
- `-P, --perl-regexp`
- `-i, --ignore-case`
- `-w, --word-regexp`

This will also allow for someone with `grep.patternType` or
`grep.extendedRegexp` set in git's config to change the pattern type.
