DuetPkg BootSector: fix bugs in .S files so that 32-bit and 64-bit DUET can boot to Shell with boot sector binaries built by GCC.

There is also a bug in bs32.asm/bs32.S that the space between the code and the 0xAA55 ending signature is not enough to hold the 2 debug strings. It is fixed by shortening the strings.
