Include the nanoBSD make.conf in the top-level nanoBSD Makefile, so

all configuration knobs (both system settings and nanoBSD-specific ones)
can be tuned by modifying a single file. Move KERNCONF default value
to make.conf.

Attempt to resolve CFGMASTER like CUSTOMIZE, first relative to ${.CURDIR},
then as an absolute path.

Allow optional additional arguments to be passed to the CUSTOMIZE script.
