BaseTools/build: Set MakefileName

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3653

Running the following command:
  python3 build/build.py -a AARCH64 -t GCC5
  -p ArmPlatformPkg/ArmPlatformPkg.dsc -b DEBUG libraries
triggers the following error:
  make: *** Build/ArmPlatform/DEBUG_GCC5/AARCH64/MdePkg/Library/
  BasePcdLibNull/BasePcdLibNull: Is a directory.  Stop.

Indeed, MakefileName is set to en empty string. Setting MakefileName
resolves the error.
