[PATCH] cvsimport: always pass user data to "system" as a list

[Jeff King <peff@peff.net>]

This avoids invoking the shell. Not only is it faster, but
it prevents the possibility of interpreting our arguments in
the shell.

Nigel reported a problem with a CVS branch that had '(' in the name. No
report yet on whether this fixes it, but it should be done regardless.

I checked over git-cvsimport.perl, and this was the only instance I
found.
