BaseTools/GenFw: align RVA of debug
SVN commit r18077 ("BaseTools/GenFw: move .debug contents to .data to
save space") removed the separate .debug section after moving its
contents into .text or .data. However, this change does not take into
account that some of these contents need to appear at a 32-bit aligned
offset. So align the debug data RVA to 32 bits.
