Replace use of variable-length-arrays.

* common/t-iobuf.c (main): Replace variable-length-array.
* g10/gpgcompose.c (mksubpkt_callback): Ditto.
(encrypted): Ditto.
* g10/t-stutter.c (log_hexdump): Ditto.
(oracle_test): Ditto.
* g10/tofu.c (get_policy): Ditto.  Use "%zu" for size_t.
* scd/app-openpgp.c (ecc_writekey): Replace variable-length-array.
Check for zero length OID_LEN.
