[OE-core] [PATCH] package_deb: Ensure allarch deb packages aren't target specific

[Richard Purdie]

The use of TUNE_FEATURES was making do_package_write_deb of allarch
packages target specific.

To avoid this, only use the end value of DPKG_ARCH for its checksum,
not intermediate values or variables.
