spectrumPackages: update execline backtick uses

execline 2.8.0.0 changed how backtick's options work:

 * -i (exit with the program's error code on failure) and -n (chomp off
   a trailing newline from the captured output) are now the defaults.
 * -E has been introduced, which does importas automatically.

-E is fantastic, because we followed every single use of backtick with
importas.

Even we didn't have -n before, it's okay that chomping will now be
enabled from the default, because in all those cases, there won't be a
trailing newline anyway.
