[PATCH] fix OS release identification in pkg_install on aix

[J Raynor <jxraynor%gmail.com@localhost>]

pkg_install doesn't correctly identify the OS release on aix, leading
to the following warning when installing a package:


===> Install binary package of tnftp-20151004
pkg_add: Warning: package `tnftp-20151004' was built for a platform:
pkg_add: AIX/powerpc 6.1 (pkg) vs. AIX/powerpc 1 (this host)


The problem is that pkg_install expects uname's release field to
contain the full OS version number, which isn't true on aix.  For
example, aix version 6.1 will have a 6 in the version field, and a 1
in the release field.  This is why the warning message above seems to
indicate that the package is being installed on aix 1 but was built on
6.1.

I've attached a patch that fixes the problem.
