[gentoo-catalyst] [PATCH 1/2] modules/generic_stage_target.py, Create SOURCE_MOUNTS_DEFAULTS

[Brian Dolbec <dolsen@gentoo.org>]

Similarly to TARGET_MOUNTS_DEFAULTS this is a temporary location.
This will simplify the migration to being fully configurable.
It also simplifies initialization somewhat.
