UKI: Fix the size of real payload
According to the PE file specification, each section's SizeOfRawData
must be a multiple of FileAlignment (usually 512). So when ukify builds
a UKI image, it pads the kernel image, initrd, etc. with zeros aligned
to 512 bytes. The actual payload size is recorded in VirtualSize.
Since the checksum includes the trailing zeros, this causes issues when
loading a signed x86 bzImage, which is stored in the UKI's .linux
section.
Credit goes to Philipp, who analysed and pointed out this issue to me.
