ci: also export NIM_PARAMS so nimble tasks see -d:disableMarchNative

The Makefile feeds nimble via the exported NIM_PARAMS variable
(see Makefile lines 115-152). NIMFLAGS alone is not propagated
to nim invocations like 'nimble testcommon', so the previous
commit had no effect on the make-driven test path. Setting
NIM_PARAMS ensures the flag reaches the nim compile line.
