rev: Normalize the reported offset of found gadgets
ROP gadgets returned through search from the r2 API will now always
contain a file-relative offset, even if they come from a non-pic binary
using a fixed baddr.
However, gadgets returned through the ELF API will be mapped according
to the ELF's Symtbl. This ensures the correct offset is returned
following a library leak, and allows the user to always safely insert an
ELF-returned gadget into that ELF's Symtbl without issue.
