ramips: rt3883: use seama-lzma-loader for D-Link DIR-645

In the support topic [0] of the GitHub issue #10634 it was found out
(based on boot logs) that the uimage-lzma-loader (commit 09faa73c53bd)
never worked, as an earlier workaround (commit 6fba88de1913) negated
the recipe:

Using the new seama-lzma-loader it's able to boot OpenWrt 22.03
and OpenWrt SNAPSHOT too:
