ath-prop-tools: fix package installation from prebuilt binaries

athtestcmd and wmiconfig are proprietary tools from Atheros. When
installed from GitHub we use prebuilt binaries because we cannot provide
the source code to the customers.

The prebuilt binaries need to be platform dependent, because the
'ccardimx28' uses soft-float binaries while the 'ccimx6' uses hard-float
binaries. Otherwise there is a failure:

root@ccimx6sbc:~# /usr/sbin/athtestcmd
-sh: /usr/sbin/athtestcmd: not found

While on it, removed the checksums for the binaries, as Yocto does
not verify checksums for local files by default, only for downloaded
files.
