package/elf2flt: add support for XTENSA_[PN]DIFF relocations
Xtensa have added new relocation types R_XTENSA_[NP]DIFF{8,16,32} with
the same properties as the existing types R_XTENSA_DIFF{8,16,32}.
Add them to the list of ignored relocation types.
This fixes the following error when invoking elf2flt on xtensa binaries
built with the recent binutils:
