etc/functions: Improve handling of battery charge/health calcs

Browse Source 
Some devices, like older Librem laptops, use BAT vs BAT0 for the
primary battery. Accomodate this by using BAT* instead of BAT0.

Could break on multi-battery devices, but none supported in tree
currently so more of a theoretical problem.
