docker: Add support for setting umask (#9429)

Add support for setting umask value in the Docker `entrypoint.sh`
script. This is useful when
not syncing permissions and working with groups, and needing umask
values like `002` instead of `022`.

`PCAP` environment variable with the same syntax as that for `setcap(8)`.
For example, `PCAP=cap_chown,cap_fowner+ep`.
To set a different umask value, use the `UMASK` environment variable. For
example `UMASK=002`.
## Example Usage
