flua: kick out the remaining builtin modules

Bootstrap flua has some magic now to handle modules by building them in
and discovering them via linker sets. This is slightly cleaner than
always building them in and baking them into loadedlibs for both
bootstrap and system flua.

Adjust the stand build now that these three libs have their own new
homes.

Revert "flua: kick out the remaining builtin modules"

This reverts commit 80ada959004c4386880e47b11618f8abfc2d80e1, because
bootstrap flua is about to get backed out.

Add flua to the base system, install to /usr/libexec

FreeBSDlua ("flua") is a FreeBSD-private lua, flavored with whatever
extensions we need for base system operations. We currently support a subset
of lfs and lposix that are used in the rewrite of makesyscall.sh into lua,
added in r354786.

flua is intentionally written such that one can install standard lua and
some set of lua modules from ports and achieve the same effect.

linit_flua is a copy of linit.c from contrib/lua with lfs and lposix added
in. This is similar to what we do in stand/. linit.c has been renamed to
make it clear that this has flua-specific bits.

luaconf has been slightly obfuscated to make extensions more difficult. Part
of the problem is that flua is already hard enough to use as a bootstrap
tool because it's not in PATH- attempting to do extension loading would
require a special bootstrap version of flua with paths changed to protect
the innocent.

src.lua.mk has been added to make it easy for in-tree stuff to find flua,
whether it's bootstrap-flua or relying on PATH frobbing by Makefile.inc1.
