Shellcheck fixes for configure.sh and steamrt-bootstrap.sh

Browse source 
In steamrt-bootstrap,sh
  + Used quotes to prevent word splitting SC2046
  + Used $() notation rather than legacy backtick SC2006
  + which is non-standard. 'command -v' is builtin SC2230

In configure.sh
  + Assigned to local variable separately to avoid masking return values SC2155
  + Used to quote to prevent glob matching SC2053
  + Used -z command rather than ! -n SC2236
  + Fixed SC2129 which would have a minor performance gain of avoiding constantly opening and closing the makefile.
