Bump bpf-tools to v1.25

- Tweak linker script
  Ensure that all read only sections end up in one segment, and
  everything else in other segments. Discard .eh_frame, .hash and
  .gnu.hash since they are unused.
- Don't create invalid string slices in stdout/stderr on Solana
- Report exceeded stack size as a warning if dynamic frames are off
- Native support for signed division in SBF
  Adds BPF_SDIV, which is enabled only for the SBF subtarget.
- Introduce dynamic stack frames and the SBFv2 flag
  Dynamic stack frames  are currently opt-in and enabled setting
  cpu=sbfv2. When sbfv2 is used, ELF files are flagged with
  e_flags=EF_SBF_V2 so the runtime can detect it and react
  accordingly.
