gstreamer1: Disable debug + other fixes

Disabled a bunch of debug stuff in order to save size.

Also removed the rpath stuff as that has not been needed for a long time.

Added PKG_BUILD_PARALLEL for faster compilation.

Removed two patches that have --disable configure parameters now.

Refreshed patches.

Size of libgstreamer1 from 822243 to 529366 on mvebu.
