[PATCH v2 2/2] roms/edk2: Only initialize required submodules

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

The EDK2 firmware images built to test QEMU do not require
the following submodules:

 - MdeModulePkg/Universal/RegularExpressionDxe/oniguruma
 - UnitTestFrameworkPkg/Library/CmockaLib/cmocka

The only submodules required are:

 - ArmPkg/Library/ArmSoftFloatLib/berkeley-softfloat-3
 - BaseTools/Source/C/BrotliCompress/brotli
 - CryptoPkg/Library/OpensslLib/openssl
 - MdeModulePkg/Library/BrotliCustomDecompressLib/brotli

Adapt the buildsys machinery to only initialize the required
submodules.
