package/pps-tools: bump version to fix usage without bash

As reported in bug #11426, the ppsfind shell script uses /bin/bash,
but the Buildroot pps-tools package doesn't depend on bash. In fact,
upstream has fixed the problem, and the script can now be used with a
POSIX shell, and the shebang is /bin/sh.

This commit therefore bumps pps-tools to the latest upstream commit,
which is precisely this fix.

Fixes bug #11426.
