kbuild: clean up scripts/Makefile.host
The directory creation can be more simplified by two levels.
[1] Drop $(dir ...)
$(dir $(f)) always returns non-empty string.
So, $(if $(dir $(f)),$(dir $(f)) is equivalent to $(dir $(f)).
[2] Unroll $(foreach ...) loop
$(dir ...) can take one or more arguments and returns a list of
directories of them.
$(foreach f, $(progs), $(dir $(f))) can be unrolled as $(dir $(progs)).
