bash: Fix git stash alias setting

Fixed bash alias loading for additional modules by loading both general
sh aliases as well as individual bash aliases.

Moved git stash push/save aliasing to split between bash/zsh shell since
zsh can check for the correct version of git to invoke push command
(only part of git since 2.13) and bash simply falls back to save.
