Subject: makechrootpkg: handle makepkg_args better

 - handle it as an array
 - have the usage text print out the actual default args, instead of the
   defaults plus whatever has been parsed before `-h`
 - getopts turns any unknown flag into `-?`; don't add `*)` to makepkg_args
 - use in_array to see if it contains -R instead of looping ourselfs
 - pass it as a series of flags to /chrootbuild; preserving whitespace.
