Include `bc` in SCALE

[dak180]

Problem/Justification
bc is included in core and is required to do more complex math in scripts such as TrueNAS-Report.

Impact
Minimal impact For those that do not need a command line based calculator

User Story
I envision users being able to use scripts like TrueNAS-Report that require complex math without requiring the user to install additional software in the base system.

Further interest?

It looks like bc can be replaced by awk in the script.

+1 for bc

Unfortunately I use ‘awk’ as well, but when you do not have ‘bc’, this is the alternative, and it’s not very difficult to use. I too would like ‘bc’ added but we have asked for it several times in the past. I’m not getting my hopes up.
