[PATCHv3] Introduce an --enable-theme="theme1 theme2..." option

[Sebastian Spaeth]

By default, we include all defaults as before, but if given, we can
limit the number of included themes with e.g. --enable-theme="oxygen
tango". This is passed through set_soenv and sets the environment
variable ENABLE_THEMES="...." which can be used by the packimages
makefile in the postprocess repository. It also adds defines in the
form of THEME_OXYGEN that are being used in the scp2 module to decide
if we should install the theme file or not.
