kconfig argcomplete: support full pkgname (MR 2134)

Support full linux-* package names in argument completion for
"pmbootstrap kconfig ..." command-lines and get rid of related PROTIP
messages:
  PROTIP: You can simply do 'pmbootstrap kconfig check postmarketos-allwinner'

This improves consistency, as in other places we expect the user to
supply full package names as well (e.g. pmbootstrap build).
