[PATCH 1/2] builtin/add: remove obsoleted support for legacy stash -p

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

90a6bb98d1 (legacy stash -p: respect the add.interactive.usebuiltin
setting, 2019-12-21) adds a hidden option and its supporting code
to support the legacy stash script, but that was left behind when
it was retired.

mostly revert commit.
