[Patch] BaseTools: Fix the bug for RAW file alignment value support

[Yonghong Zhu <yonghong.zhu@intel.com>]

Fix the bug for RAW file to support Align=32 and Align=64. Current FDF
spec FfsAlignmentValues support this two values, while it is not the
valid value for GenFfs. So this patch add the logic to handle it.
