PKGBUILD.vim: improve 'options' highlighting, add extra keywords

This fixes the current syntax highlighting behavior in the 'options'
array, which does *not* flag illegal options (e.g. typos, unsupported
options). The shDoubleQuote and shSingleQuote options were the culprits.
Now, if you enter `'!imptydurs'`, the typoed option will be flagged red.

I also added syntax highlighting for the new options listed in `man 5
makepkg.conf`, which I believe were introduced around pacman 4.0.0.
