Fix lxc syntax-check failure

Fixes:

 CHECK: avoid_if_before_free
 src/lxc_container.c: if (oldroot) VIR_FREE(oldroot)
 src/lxc_container.c: if (newroot) VIR_FREE(newroot)
 Makefile.maint: found useless "if" before "free" above

and:

 src/lxc_container.c:317:
 Makefile.maint: found trailing blank(s)
