    CTF testsuite: Remove explicit check on ctv_typeidx
    
    The value of ctv_typeidx is the CTF type ID of the data type of the associated
    variable.  The order in which the CTF types are added can change across
    platforms and also as the code evolves, hence changing the CTF type ID. As
    there is no direct and portable method of testing that the data type of a CTF
    variable is of a specific kind, remove the check on ctv_typeidx.
    
    This also fixes a subset of failures as seen on Darwin.
