As of v5.11-rc1, 12 architectures duplicate similar shell scripts in
order to generate syscall table headers. My goal is to unify them into
the single scripts/syscalltbl.sh.
This commit converts mips to use scripts/syscalltbl.sh. This also
unifies syscall_table_32_o32.h and syscall_table_64_o32.h into
syscall_table_o32.h.
