Add add-auto-load-scripts-directory.

Browse Source 
There is already "add-auto-load-safe-path" which works
like "set auto-load safe-path" but in append mode.

There was missing an append equivalent for "set auto-load scripts-directory".

ABRT has directory /var/cache/abrt-di/ as an alternative one
to /usr/lib/debug/ . Therefore ABRT needs to use -iex parameters to add this
/var/cache/abrt-di/ directory as a first-class debuginfo directory.
Using absolute "set auto-load scripts-directory" would hard-code the path
possibly overriding local system directory additions; besides it would not be
nice anyway.
