Don't special case $(XZCAT) when constructing DL_TOOLS_DEPENDENCIES. The next
commit will introduce another extractor that automatically builds when not
installed. Introduce EXTRACTOR_DEPENDENCY_PRECHECKED_EXTENSIONS that lists
archive extensions for which the extractor is already checked in
support/dependencies/check-host-foo.mk. Use this in the newly introduced
extractor-dependency to populate DL_TOOLS_DEPENDENCIES.

If xzcat is not present on the host system, buildroot bails out early asking
the developer to install it (xzcat is now a DL_TOOLS_DEPENDENCY)
Conversely, when BR2_TARGET_ROOTFS_CPIO_XZ is enabled, then host-xz is a
build dependency, and no manual action is required from the developer.
Because the second approach is nicer, also build host-xz when xzcat is not
available, using the host-prerequisite and suitable-host-pkg mechanisms,
already used for tar.
