last-modified: add option '--max-depth' to help output

Browse Source 
In previous commit option '--max-depth' was added to the documentation.
To have it also appear in the help output of `git last-modified -h`,
move the handling of '--max-depth' to parse_options() in
builtin/last-modified.c itself.

It enables us to change default behavior in a subsequent commit.
