resource/aws_glue_crawler: Prevent error when deleted outside Terraform

[bflad]

Similar fix as #5141 (with aws_glue_catalog_database) but for aws_glue_crawler

Changes proposed in this pull request:

• Return false with EntityNotFoundException error instead of that error in aws_glue_crawler exists function

Previously:

$ make testacc TEST=./aws TESTARGS='-run=TestAccAWSGlueCrawler_recreates'
==> Checking that code complies with gofmt requirements...
TF_ACC=1 go test ./aws -v -run=TestAccAWSGlueCrawler_recreates -timeout 120m
