intltool: depend on hostpkg first

The scripts will use the $(STAGING_DIR)/bin/perl which is a simlink to native
perl, using $(STAGING_DIR_HOSTPKG) first will use the "perl/host" that has
multiple modules availabe to be built as host like perl-xml-parser

Using the $(STAGING_DIR)/bin/perl pakages that depend on "perl-xml-parser/host"
will fail with:

You must have XML::Parser installed to run
