description:
sys/conf: remove useless dollars from Makefile.kern.inc

When parsing a variable modifier such as :C or :S, all '$' but the very
last are silently swallowed.

See usr.bin/make/unit-tests/varmod-subst.mk for details.

Since August 2020, make has a strict lint mode that is activated by
passing it the option -dL.  In that mode, these redundant '$' are not
accepted anymore.
