asn1_SUITE: Mend broken test_modified_x420/1

The test_modified_x420/1 test case had several problems that
prevented it to detect the bugs it was supposed to find:

1) There was a 'catch' at the top-level so that it could never fail.
2) There was a call to the now non-existing ssl_base64 module.
3) It did not test all options for the BER backend.

While at it, also clean way the remaining ?line macros and some
out-commented code.
