multiple grin wallet instances do not work in firejail

[bitcoal]

for example, you can run one of these commands but trying to run both will always crash

firejail --private=grinjail grin wallet listen
firejail --private=grinjail grin wallet owner_api

Multiple wallet instances will conflict with each other's ports unless they're properly configured. Please feel free to open an enhancement issue if you feel firejail should be supported.
