create-user-key-store.sh: Fix defect about invalid option "--pinentry-mode=loopback"

The option --pinentry-mode is not supported in gpg 2.0.22 code.
so when the host gpg version is 2.0.22 the option will be removed.
Start gpg-agent daemon when gpg-connect-agent reload agent failed.
Otherwise there will be below failure message reported.
gpg: can't connect to the agent - trying fall back
gpg: can't connect to the agent: IPC connect call failed
gpg: problem with the agent: No agent running
