app-shells/bash: Fix the builtin man pages

[orbea]

When using stricter man implementations such as app-text/mandoc the builtin man pages (i.e. man export) fail to display most of the manual unless the path for the bash.1 man page is correct.

I submitted this patch upstream in 2018 for Slackware who now carries this patch, but upstream wasn't very understanding suggesting distros should carry it themselves.

Chet mentions the install_builtins target... why don't we just call that instead?

[orbea]

The install_builtins target only covers builtins.1 and not rbash.1. It also changes the file name from builtins.1 to bash_builtins.1, but that is probably an improvement.

I could use install_builtins and slim down the patch to only rbash.1?

Edit: I see you already got there, thanks!
