Subject: [PATCH] timesync, meson: allow statically linked build

Build option "link-timesyncd-shared" to build a statically linked
systemd-timesyncd by using

  -Dlink-udev-shared=false -Dlink-timesyncd-shared=false

on systems with full systemd stack except systemd-timesyncd, such
as RHEL/CentOS 8.
