LSB Command Check: fix install_initd and remove_initd not found

The install_initd and remove_initd are linked to /sbin/chkconfig for lsb
core test, but chkconfig has been moved from /sbin to /usr/sbin in order
to fix QA warning about unsafe references in binaries.
(In commit e486242db83297701803866bea971a2f1a1135fe)

Let install_initd and remove_initd link to /usr/sbin/chkconfig could fix
this issue.
