package/elf2flt: bump version to fix build with binutils >= 2.32

Binutils added bfd_stdint.h to bfd.h [1], so elf2flt must create a
symlink for this header. This issue has been fixed upstream in commit
[2].

We keep our local patch
0001-ld-elf2flt-behave-properly-when-called-with-a-name-d.patch as it
still hasn't been merged upstream [3].

Fixes (with binutils 2.23):
