Bug 2067485. Run third_party/js/cfworker/build.sh with bash, since that is what it is written in. r=mossop

build.sh says #!/bin/sh but its second line is `set -euo pipefail` and line 7 uses `[[ ]]`,
neither of which is POSIX sh.

Bash is commonly used in other moz.yaml scripts, so this is nothing new.
