[OE-core] [PATCH] util-linux.inc: add fallocate & unshare to alternatives

[Martin Jansa]

This is good, but the fallocate alternative should be added only for target
build.

nativesdk explicitly disables fallocate in
meta/recipes-core/util-linux/util-linux_2.32.bb

EXTRA_OECONF_class-nativesdk = "${SHARED_EXTRA_OECONF} \
                                --disable-fallocate \
                                --disable-use-tty-group \
"

so now nativesdk builds have new warning:
WARNING: nativesdk-util-linux-2.32-r0 do_package: util-linux: alternative
target (sdk/usr/bin/fallocate or sdk/usr/bin/fallocate.util-linux) does not
exist, skipping...
WARNING: nativesdk-util-linux-2.32-r0 do_package: util-linux: NOT adding
alternative provide sdk/usr/bin/fallocate: sdk/usr/bin/fallocate.util-linux

WARNING: nativesdk-util-linux-2.32-r0 do_package: util-linux: alt_link ==
