SecurityPkg: don't require PK to be self-signed by default
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2506
Change the default value of PcdRequireSelfSignedPk to FALSE in
accordance with UEFI spec, which states that PK need not be
self-signed when enrolling in setup mode.
Note that this relaxes the legacy behavior, which required the PK to
be self-signed in this case.
