[OE-core] [PATCH v2 1/1] goarch.bbclass: rework mips architecture checks

[Matt Madison]

Remove the TUNE_FEATURES references from go_map_arch,
to avoid an unwanted variable dependency.  Direct
comparisons of the architecture name are sufficient
for covering what Go currently supports, and using
TUNE_CCARGS_remove adequately handles the conflict
with the cgo-supplied flags for mips.
