alias: use run_command api to execute aliases
On Windows, system() executes with cmd.exe instead of /bin/sh. This
means that aliases currently has to be batch-scripts instead of
bourne-scripts. On top of that, cmd.exe does not handle single quotes,
which is what the code-path currently uses to handle arguments with
spaces.
To solve both problems in one go, use run_command_v_opt() to execute
the alias. It already does the right thing prepend "sh -c " to the
alias.
