Fix cyclic dependency error on OptionROM build

Fix cyclic dependency error on OptionROM build

EDKII build system supports OptionROM generation if particular PCI_*
defines are present in the module INF file:
```
[Defines]
  ...
  PCI_VENDOR_ID                  = <...>
  PCI_DEVICE_ID                  = <...>
  PCI_CLASS_CODE                 = <...>
  PCI_REVISION                   = <...>
```
Although after the commit d372ab585a2cdc5348af5f701c56c631235fe698
("BaseTools/Conf: Fix Dynamic-Library-File template") it is no longer
possible.
The build system fails with the error:
```
Cyclic dependency detected while generating rule for
"<...>/DEBUG/<...>.efi" file
```
Remove "$(DEBUG_DIR)(+)$(MODULE_NAME).efi" from the 'dll' output files
to fix the cyclic dependency.
