[yocto] [meta-gplv2][PATCH] gnupg: specify tar path explicitly

[Yi Zhao]

From: Wenlin Kang <wenlin.kang at windriver.com>

The gpg-zip script contains wrong tar binary path:
"TAR=/buildarea/poky/build/tmp/hosttools/tar"

Specify the correct tar path when configure.
Also remove the code for ustar format detection in configure because it
is not applicable for cross-compile environment.
