sh: Remove remnants to compile out fc completely

r360139 made compiling with NO_HISTORY work. This #define does not remove
the fc and bind builtins completely but makes them always write an error
message.

However, there was also some code in builtins.def and mkbuiltins to remove
the fc builtin entirely (but not the bind builtin). The additional build
system complication to make this work seems not worth it, so remove that
code.

Don't hardcode /usr/bin as the path for mktemp in build tools

It won't work e.g. when crossbuilding from Ubuntu Linux as mktemp is in

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same

Work better with how make/bmake works:
1. Avoid a cd back into ${.CURDIR} to run mkbuiltins when we know make
will first cd into ${.OBJDIR}. Keep the cwd to what make sets it to.
2. Don't tell mkbuiltins where to write to (= ${.OBJDIR}), but where to
get sources from (= ${.CURDIR}). This to compensate for point 1.

This fixes a problem with bmake's mk files that optimize ${.OBJDIR} to
expand to "." after changing cwd, not taking into account that the
target is pretty much undoing that and not getting the full path to the
object tree anymore.
