[PXE] Improve PnP/BBS detection
Use BBS installation check to see if we need to hook INT19 even on a PnP
BIOS.
Verify that $PnP signature is paragraph-aligned; bochs/qemu BIOS provides
a dummy $PnP signature with no valid entry point, and deliberately
unaligns the signature to indicate that it is not properly valid.
Print message if INT19 is hooked.
Attempt to use PMM even if BBS check failed.
