[COMMON] Fix array variables increments

pointed out by checkbashisms in docker-entrypoint.sh

- migrate to straight strings the arrays used to pass options
Arrays are supported in bash but are not POSIX compliant.

- remove useless double quotes in variables used to pass options
Double quotes are often used to avoid globbing and word splitting.
Since possibles values are strictly constrained here, they are not
required.
