configure.ac: don't let -lcgmanager end up in LIBS
configure.ac: don't let -lcgmanager end up in LIBS

AC_SEARCH_LIBS always places the library being queried into LIBS.  We
don't want that - we were only checking whether a function is
available.  Not everything (notably not init.lxc.static) needs to
link against -lcgmanager.
