Since the separate binaries contain mostly the same code,
this almost halves the size of the installation.
before:
398K /bin/udevadm
391K /lib/systemd/systemd-udevd
after:
431K /bin/udevadm
0 /lib/systemd/systemd-udevd -> ../../bin/udevadm
Fixes: #14200
Kernel 4.1 separated the tracing system from the debugfs,
actual documentation already points to a different path
that needs this new mount to exist.
the old sysfs path will still be an automount in the debugfs,
created by the kernel (for now).
