And as always when writing tests you find some corner cases :)
So the attached is some testcases plus some fixes:
- Handle files without sections (only phdrs), in particular handle
  PT_DYNAMIC directly (not through a section).
- is_loadable should check whether it isn't a debug-only file
  (but only if there are section headers, if not, it cannot be debug-only).
- For .debug_only we can also have just a .symtab (but no .debug sections).
  And any allocated section makes it not-debug-only (except for SHT_NOBITS
  or SHT_NOTE)
- Detect .zdebug sections too (old GNU compressed ELF sections).

Cheers,

Mark
