[8u] RFR (S) 8193137: Nashorn crashes when given an empty script file

[Aleksey Shipilev]

Original bug:
  https://bugs.openjdk.java.net/browse/JDK-8193137
  https://hg.openjdk.java.net/jdk/jdk/rev/ef5199ed52f0

Patch applies with reshuffles, but the test needs more work:
  - dropped --patch-module line
  - added the block that defines "fail" (like in sibling tests)

8u webrev:
  https://cr.openjdk.java.net/~shade/8193137/webrev.8u.01/

Testing: tier1, new test
