    exec: Return 126 on most errors in shellexec

    Currently when shellexec fails on most errors the shell will exit
    with exit status 2.  This patch changes it to 126 in order to avoid
    ambiguities with the exit status from a successful exec.

    The errors that result in 127 has also been expanded to include
    ENOTDIR, ENAMETOOLONG and ELOOP.
