Fix No spread on the hl2_complete server build

The server RandomSeed GOT slot was hardcoded to 0xce1348, measured on the
older bin/server.so. The anniversary branch loads hl2_complete/bin/server.so,
whose R_386_JMP_SLOT for RandomSeed is 0xce5348, so the patch hit unrelated
writable data and no spread silently did nothing.

- Read the relocation from the loaded module's ELF (module_jump_slot) instead
  of hardcoding, with the two known offsets as fallback.
- Override whenever the RandomSeed caller's `this` is the local server player
  (CBaseEntity::FireBullets) instead of matching a hardcoded return-address
  range that also moved between builds.
- m_takedamage is a char (FIELD_CHARACTER) in the 2013 SDK; resolve it as such
  and read a byte, so the IMMUNE damage tag actually works.
