[enhancement] add an option to remove libndk/libhoudini

[ghost]

I accidently insatlled both libndk and libhoudini and now I can't run waydroid. It would be better in i could remove any of them through the script.

Maybe we could track the file during installation file and save them ? It will be easier to remove the file from package that got updated while the user had older installed ! Maintenance may also be easier as we won't have to make a list of files that got changed after a package update ! For clean uninstallation of houdini and other stuff using props, a unset_props method in general that takes each keys of app_props dict and does re.sub(f'^{prop_key}.*$', '', current_prop) would be enough too !

def unset_props(self):
    with open(os.path.join("/var/lib/waydroid/waydroid_base.prop"), "r") as propfile:
        prop_content = propfile.read()
        for key in self.apply_props:
            prop_content = re.sub(f'^{key}.*$', '', prop_content) # We may need to save value if prop already existed during install and we have backup for it's key/value and set the second parameter of re.sub to "  f'{key}:{old_value}'  "
    with open(os.path.join("/var/lib/waydroid/waydroid_base.prop"), "w") as propfile:
        propfile.write(prop_content)

If this saved file is accidentally deleted, the user will not be able to complete the uninstallation.

Yea, I did add this method. https://github.com/ayasa520/waydroid_script/blob/200e18bb0d03ce1cbdd88e9b28a95b8b2d526f80/stuffs/general.py#L74-L82

/system/etc/init/xxx.rc will still be executed after clearing the key-value pairs in prop file, so I think it's better to delete it completely
