infinite loop when userscript fails

[erikng]

if a userscript fails, installapplications doesn't remove the touch file, so you get into an infinite loop.

    if opts.userscript:
        iaslog('Running in userscript mode')
        uscript = runuserscript(iauserscriptpath)
        if uscript:
            os.remove(userscripttouchpath)
            sys.exit(0)
        else:
            iaslog('Failed to run script!')
            sys.exit(1)

should be

    if opts.userscript:
        iaslog('Running in userscript mode')
        uscript = runuserscript(iauserscriptpath)
        if uscript:
            os.remove(userscripttouchpath)
            sys.exit(0)
        else:
            iaslog('Failed to run script!')
            os.remove(userscripttouchpath)
            sys.exit(1)
