  stand/liblua: fix loader build with lua 5.4.7 (restore LUA_AVOID_FLOAT)

The lua 5.4.7 vendor import reverted the local patches that keep the
bootloader's float-free (LUA_FLOAT_INT64) Lua build working, and the
INT64 hack in stand/liblua/luaconf.h still defined the old 5.3-era
l_mathlim macro instead of the 5.4 l_floatatt name.  As a result the
loader failed to build (l_floatatt/MANT_DIG undeclared, the invalid
token lstd_1.0 from l_mathop(ldexp)(l_mathop(1.0), ...), and float/
double/HUGE_VAL code tripping the loader's keyword poison).

Restore the FreeBSD LUA_AVOID_FLOAT mechanism:
- stand/liblua/luaconf.h: rename l_mathlim -> l_floatatt (used by
  lstrlib.c MAX_ITEMF and lvm.c NBM) and #define LUA_AVOID_FLOAT for the
  LUA_FLOAT_INT64 build.
- contrib/lua/src/lcode.c: guard the float-key path in luaK_numberK.
- contrib/lua/src/lstrlib.c: guard the C float/double pack/unpack,
  quotefloat, and %f format paths.

Verified by building stand/liblua for amd64.
