This fix is recommended here [0]. I couldn't figure out a cleaner way to
do this. It would have been a more stable patch against `config.ac`, but
`configure` is included in the source tarball and this seemed like the
lesser evil.

In issue https://github.com/termux/termux-packages/issues/6160 I have found
that community repo "its-pointless.github.io" specifies us as maintainer
for its packages. This is NOT TRUE and potentially misleads people using
these packages.
Now TERMUX_PKG_MAINTAINER will contain a default value which is neutral
and not specify maintainer. So all packages now have to override it to
the correct value.
