[PATCH for 6.3] MIPS: Define RUNTIME_DISCARD_EXIT in LD script

[Jiaxun Yang <jiaxun.yang@xxxxxxxxxxx>]

MIPS's exit sections are discarded at runtime as well.

Fixes link error:
`.exit.text' referenced in section `__jump_table' of fs/fuse/inode.o:
defined in discarded section `.exit.text' of fs/fuse/inode.o

Fixes: 99cb0d917ffa ("arch: fix broken BuildID for arm64 and riscv")
