Hard links do not work on Android since 6.0.
So modify the file locking mechanism from:
if ln "$tmpfile" "$lockf"; then rm -f "$tmpfile"; ..
to
if mv --update=none-fail "$tmpfile" "$lockf"; then ..
Fixes#21736
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.
