Fixed BUG#11365: Stored Procedure: Crash on Procedure operation

  Two separate problems. A key buffer was too small in sp.cc for multi-byte
  fields, and the creation and fixing of mysql.proc in the scripts hadn't been
  updated with the correct character sets and collations (like the other
  system tables had).
  Note: No special test case, as the use of utf8 for mysql.proc will make
  any existing crash (if the buffer overrrun wasn't fixed).


mysql-test/r/sp-error.result:
  Updated test case for too long SP names (as the limit has increased with the use of utf8).
mysql-test/t/sp-error.test:
  Updated test case for too long SP names (as the limit has increased with the use of utf8).
scripts/mysql_create_system_tables.sh:
  Use utf8 for mysql.proc, just like for the other system tables.
scripts/mysql_fix_privilege_tables.sql:
  Use utf8 for mysql.proc, just like for the other system tables.
  (Some tabs also replaced by space)
sql/sp.cc:
  Use a larger key buffer for stored procedures to avoid stack overrun with multi-byte keys.
