[mbr] use 80x25:16 text mode rather than 640x480:16 VGA mode
* This should produce the same output while improving compatibility with systems that have a broken VGA implementation.
* Also fix an LD error with newer gcc toolchains.

[core] fix MBR protective message overwriting the primary GPT
* We distractedly chose to populate the message from our protective MBR
  for GPT/UEFI-only boot media into the 4KB that directly followed the
  MBR, which of course is space that is being used by the primary GPT.
* This resulted on systems having to fall back to using the secondary
  GPT, which not all appear to be designed to do.
* Alter the code to ensure the protective message is written at LBA 34,
  after the primary GPT.
* Closes #1507
