Set temp directory when using shell

[ddanielr]

JLine creates a .so and a .so.lck file when interactively prompting the user for input.
The .so file needs execute permissions to function correctly.

jlinenative-3.25.1-164e07369eff3578-libjlinenative.so
jlinenative-3.25.1-164e07369eff3578-libjlinenative.so.lck

However, these files go in the directory set by java.io.tmpdir which is typically /tmp or /var/tmp and is commonly set with noexec to conform with security best practices.

This prevents Jline from functioning correctly and breaks the shell.

Instead, we can use accumulo's /run directory for these temp files as it is used for ephemeral .pid files already.

I was able to remove the execute permission in the jline code and have the shell function correctly.

Opened a PR to get that change merged upstream jline/jline3#1081.
Closing this for now.
