Makefile.inc1: Fix package-pkg with CROSS_TOOLCHAINlf/dev/pkgbase-cross-toolchain

CROSS_TOOLCHAIN is used to build src with a different toolchain than
the bundled one.  Ports also has a CROSS_TOOLCHAIN option, but it has
a different meaning.  When building ports-mgmt/pkg from ports for the
package-pkg target, unset CROSS_TOOLCHAIN to prevent ports from being
confused.

This fixes 'make CROSS_TOOLCHAIN=llvm19 package-pkg'.
