sysutils/rsftch: update to 0.7.6

Release notes:
 - Rewrite count_packs function to not be overly repetitive and use Rusts \ 
alternative for counting packages for a potential time save
 - Change GPU and uptime functions to not return a Result, as this was only a \ 
thing during debugging and simply was forgotten.
 - All functions now return "N/A" when an error occurs, instead of \ 
some returning an empty string instead.
 - Added more WSL compatablity.
 - WSL issues now listed in the README.
