package/liboauth: remove package

This package fails to build in the autobuilders:

  https://autobuild.buildroot.net/?reason=liboauth%

The last upstream release, 1.0.3, was done 11 years ago:

  https://sourceforge.net/projects/liboauth/

There is a Github repo at:

  https://github.com/x42/liboauth

with commits from 3 years ago, but no release.

We already carry a patch fixing the build with OpenSSL 1.1.x, which
has been submitted at https://github.com/x42/liboauth/issues/9 but
never merged, despite being opened since 2017.

This package also has no maintainer in DEVELOPERS, and it has no
reverse dependency in Buildroot, so let's get rid of it.

Fixes:
