I'd suggest you remove conflict items in do_install in case of native. 
An example is in coreutils recipe as below.

do_install_class-native() {
     autotools_do_install
     # remove groups to fix conflict with shadow-native
     rm -f ${D}${STAGING_BINDIR_NATIVE}/groups
     # The return is a must since native doesn't need the
     # do_install_append() in the below.
     return
}

You can create a bbappend file in your layer and do similar things.
