[ Upstream commit 2154aca21408752eaa3eeaf2ba6e942724ff2a4d ]

Commit e90886291c7c ("certs: make system keyring depend on x509 parser")
is not the right fix because x509_load_certificate_list() can be modular.

The combination of CONFIG_SYSTEM_TRUSTED_KEYRING=y and
CONFIG_X509_CERTIFICATE_PARSER=m still results in the following error:

LD .tmp_vmlinux.kallsyms1
ld: certs/system_keyring.o: in function `load_system_certificate_list':
system_keyring.c:(.init.text+0x8c): undefined reference to `x509_load_certificate_list'
make: *** [Makefile:1169: vmlinux] Error 1

Fixes: e90886291c7c ("certs: make system keyring depend on x509 parser")
