[PATCH] include/keys/system_keyring.h: fix building error

[Cong Ding]

When I am doing "make randconfig", it causes the following building error if
CONFIG_SYSTEM_TRUSTED_KEYRING is not defined and CONFIG_MODULE_SIG is defined.

kernel/module_signing.c: In function ârequest_asymmetric_keyâ:
kernel/module_signing.c:161:36: error: âsystem_trusted_keyringâ undeclared
(first use in this function)
kernel/module_signing.c:161:36: note: each undeclared identifier is reported
only once for each function it appears in
