Subject: [PATCH] Remove license key leniency
 (elastic/x-pack-elasticsearch#4277)

If the license key specified by the system property license.key does not
exist, Gradle does not care. Gradle should care, so this commit makes it
care.

Original commit: elastic/x-pack-elasticsearch@afc0a1443c871d927233ef5ee0ba7fc3650a9fe6
