Enable MODULE_DECOMPRESS
Since commit e8b64e4b ("Compress all modules") modules are compressed via xz. Currently these modules cannot be loaded directly, like previously, via finit_module(2) but need to be decompressed in userspace and then loaded via init_module(2). This obstructs details over the source module file, e.g. SELinux is no longer able to obtain the security file context of the module to enable fine grained access control.
