perlcross: check the file if patched or not

After the commit(60dcb230f6 perl: split perl-cross into its own recipe)
introduced, the source files mainly come from two parts, one is from
SRI_URI during do_fetch and the other with below means during do_configure.
do_configure_prepend() {
    cp -rfp ${STAGING_DATADIR_NATIVE}/perl-cross/* ${S}
}

And the source files will be changed during do_compile with below
logic in Makefile.
$(CROSSPATCHED): %.applied: %.patch
        patch -p1 -i $< && touch $@

And there comes build failure with below steps:
 $ bitbake perl-native

Make a change as below
 $ git diff

 [snip]

It's because the source files patched twice, so check the file if patched
or not to avoid the source files patched more than one time to fix the
build failure as above.
