Subject: [PATCH] Fix test failures in CI build, disable Mac build (#39)

.github/workflows/ci.yml:
- Disable Mac build as the GitHub runners appear to be broken
  (e.g. SIGCHLD fails, unlike on real Macs) and tend to hang.
- For the Linux build:
  - Set GMT timezone for 'printf %T' tests in builtins.sh.
  - Set the ulimit for open files to 1024 as the subshell.sh tests
    need a lot of open files.
  - As the runners lack the POSIX standard /dev/tty device, use the
    script command to provide a fake /dev/tty for the bracket.sh
    tests that use 'test -t $fd'.
