polkit: fix do_install failure for sysvinit & libdir = "/usr/lib64"

While using sysvinit as INIT_MANAGER and libdir = "/usr/lib64" ,
polkit do_install failed at remove systemd directory

...
rm: cannot remove 'tmp/work/corei7-64-wrs-linux/polkit/126/image/usr/lib64/systemd': No such file or directory
...

Force remove ${nonarch_libdir}/systemd and ${libdir}/systemd to assure
all systemd directories clean up
