watch 3.3.10: new version and upstream switch

Updated `watch` to the latest version from the procps-ng project, a Debian, Fedora and openSUSE fork of procps. It's more up-to-date than the procps project.
In this version it also supports colored output.

This should close #34850 and fix #11476.
Otherwise it would break, since it would look for a non-existing library installed in ./proc/libprocps.la.

The output of `make watch` without the variable reset would be:
```
libtool: link: cannot find the library `./proc/libprocps.la' or unhandled argument `./proc/libprocps.la'
make: *** [watch] Error 1
```
