meta-renesas: update gstreamer version workaround

The wildcard bbappends added as a workaround for gstreamer 1.16.3
versus 1.16.2 for the dunfell 3.1.4 upgrade (SPEC-3706) were less
than ideal since they still pointed at the 1.16.2 branch in Renesas'
repositories.  They have advised that 1.16.3 support branches are
now available, so update the workaround bbappends to use them, and
change the wildcard usage back to the full version number.

This should hold us until the BSP v4.1.7 update, when these bbappends
can be removed.
