RPi4: add config.txt with default 320MB gpu mem

Several 4k HEVC files were reported to play with artifacts unless
gpu mem is bumped to at least 288MB. Use 320MB for now to have a bit
more headroom, just in case.

Unfortunately this can't be changed via distroconfig.txt so we have
to do it in config.txt.

Also drop the disable_overscan block as that's enabled by default
via distroconfig.txt.
