[PATCH] Install built-ins as symlinks

[Alp Toker <alp@atoker.com>]

Doing this now will save headache in the long run, avoiding mismatched
versions of installed utilities and dangling copies of removed or
renamed git commands that still appear to work. It also makes screwups
when packaging git or making system backups less likely.

BusyBox has been doing it this way for years.
