* cmd: Fix summary of few "L" sub-commands
* util: start decluttering plugins handling

* util: move dlopen/dlsym/dlclose to rz_sys
* util: make rz_lib_open/close return bool
* util: simplify rz_lib_add_handler and rz_lib_open*
* libs: implement rz_*_plugin_del to remove a plugin
* core: remove commands from RzCmd when removing plugins
* librz: call plugins 'fini' method when removing a plugin

When removing a group command, the inner command might have the same
name, thus it would result in trying to remove the same name twice.
Ignore it, as it is fine.
