[20/27] sh: syscalls: switch to generic syscalltbl.sh

Commit Message

Masahiro Yamada Jan. 28, 2021, 12:51 a.m. UTC

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 sh to use scripts/syscalltbl.sh.
