kconfig: Check for if conditions in Kconfig for localmodconfig
The streamline_config.pl misses the if conditions for checking
dependencies. For Kconfigs with the following construct:
if MEDIA_SUPPORT
config VIDEO_DEV
[...]
If VIDEO_DEV was enabled, the script will miss the fact that MEDIA_SUPPORT
is also needed.
This patch changes streamline_config.pl to include if conditions into
the dependencies of configs.
