OvmfPkg: disable stale fork of SecureBootConfigDxe

OvmfPkg forked SecureBootConfigDxe from SecurityPkg in SVN r13635 (git
commit 8c71ec8f). Since then, the original (in
"SecurityPkg/VariableAuthenticated/SecureBootConfigDxe") has diverged
significantly.

The initial diff between the original and the fork, when the fork was made
(ie. at SVN r13635), reads as follows:

The commit message is not overly verbose:

  OvmfPkg: Add custom SecureBootConfigDxe that doesn't reset

  We don't force a platform reset for OVMF when PK is changed in custom
  mode setup.

But the INF file hunk is telling:

  Need custom SecureBootConfigDxe for OVMF that does not force resets
  after PK changes since OVMF doesn't have persistent variables

We do have persistent variables now. Let's disable the (now obsolete)
OvmfPkg fork, and revert to the (well maintained) SecurityPkg-provided
config driver.
