[FREELDR] Some initialization fixes.

Browse source 
- Initialize BootPath and BootOptions buffers when fallback behaviour is not taken.
- Correctly skip all the understood whitespace (space & tabs) and the
  quotes before reading the boot options when using the alternative syntax:

  [Operating Systems]
  section_name = "ReactOS" /bootoptions

  Fixes the minor regression introduced in 370e8564 (r43875).
