(makefile-space, makefile-makepp-perl): Eliminate "-face" suffix.

(makefile-targets): Inherit from font-lock-function-name-face and eliminate
"-face" suffix.
(makefile-shell): Remove attributes and eliminate "-face" suffix.
(makefile-*-font-lock-keywords): Append makefile-targets in rule actions,
instead of prepending, to make it less visible.
(makefile-previous-dependency, makefile-match-dependency): Don't match a target
on a continuation line.
