Sourcing completions/bash/oci-image-tool produces:
bash: __oci-image-tool_previous_extglob_setting=shopt: command not found
bash: eval: -i: invalid option
eval: usage: eval [arg ...]
This occurs because `__oci-image-tool_previous_extglob_setting` is not a
valid variable name (see https://unix.stackexchange.com/q/23659).
Fix the variable name by replacing `-` with `_`. Since the variable is
unset before the script finishes, this presents minimal compatibility
risk.
