chrony: upgrade 4.7 -> 4.8

0001-Fix-compilation-with-musl.patch is obsolete due to
948ecf8 ("hash: include util.h for MIN macro") included in chrony since
version 3.5.

From chrony's NEWS [1] for the 4.8 release:

Enhancements
------------
* Add maxunreach option to limit selection of unreachable sources
* Add -u option to chronyc to drop root privileges (default chronyc user
  is set by configure script)

Bug fixes
---------
* Hide chronyc socket to mitigate unsafe permissions change
* Fix refclock extpps option to work on Linux >= 6.15
* Validate refclock samples for reachability updates
