d2c07dbc46 Properly disable LUA_USE_DLOPEN for bootstrap flua
flua does have some specific bits that will include luaconf.h, but the
definition of LUA_USE_DLOPEN for those won't matter. This belongs in liblua
instead.

To expand on my previous commit, which was a little sparse with details,
it's not really safe to allow LUA_USE_DLOPEN with host lib paths being used.
The host system could have an entirely different lua version and this could
cause us to crash and burn.

If we want to revive this later, we need to make sure to define c module
paths inside OBJDIR that are compiled against whatever version we've
bootstrapped.

8af5f7bc9c flua: don't allow dlopen, et al., for bootstrap flua
There are some logistics issues that need to be sorted out here before we
can actually allow this to work.

70b298c4a2 flua: initial support for "require" in the base system
Use /usr not /usr/local for base system components.

Use /usr/lib/flua and /usr/share/flua (not lua) for consistency and to
avoid the possibility that other software accidentally finds our base
system modules.

Also drop the version from the path, as flua represents an unspecified
lua version that corresponds to the FreeBSD version it comes with.

LUA_USE_DLOPEN is not yet enabled because some additional changes are
needed wrt symbol visibility.

89677cbc50 liblua: ensure that "require" will fail in bootstrap flua
We do not want to support bootstrapping lua modules, so ensure that
require will fail by providing a nonexistent path.
