x86: boot: Fix EFI stub alignment
We currently align the end of the compressed image to a multiple of 16. However, the PE-COFF header included in the EFI stub says that the file alignment is 32 bytes, and when adding an EFI signature to the file it must first be padded to this alignment. sbsigntool commands warn about this: warning: file-aligned section .text extends beyond end of file warning: checksum areas are greater than image size. Invalid section table? Worse, pesign -at least when creating a detached signature- uses the hash of the unpadded file, resulting in an invalid signature if padding is required. Avoid both these problems by increasing alignment to 32 bytes when CONFIG_EFI_STUB is enabled.
