TOOLS-4263 Convert mongorestore invalid-input tests to Go

[autarch]

This adds a new TestRestoreInvalidInput test in mongorestore/invalid_input_test.go. This covers a number of cases for mongorestore's handling of invalid input options.

It replaces many JS tests:

• bad_options.js -> "option validation" subtests: --objcheck
  with --noobjcheck, malformed --oplogLimit,
  negative --writeConcern, invalid --db,
  invalid --collection. (The -v verbosity
  case is omitted: it exercises shared
  common/options code, not mongorestore.)
• missing_dump.js -> "missing dump target" subtests (missing
  dir, missing dir with --db, missing bson
  file with --collection)
• invalid_dump_target.js -> "invalid dump target" subtests (file where
  a dir is expected, with and without --db;
  dir where a bson file is expected)
• malformed_bson.js -> "malformed bson file errors"
• malformed_metadata.js -> "malformed metadata file errors"
• invalid_metadata.js -> "invalid index in metadata errors"
• blank_collection_bson.js -> "blank collection bson" subtests (with and
  without a metadata file)
• blank_db.js -> "blank db directory succeeds"
• objcheck_valid_bson.js -> "objcheck succeeds on valid bson"
• oplog_replay_no_oplog.js -> "oplogReplay with no oplog file errors"
