Fix compilation failure related to jplag.frontend.java-1.5/pom.xml

[erikmd]

Hello,

When compiling JFlag with Maven 3.2.5 and running the following command in the jflag root folder:

$ mvn clean generate-sources package

I was getting a compilation failure:

(...)

and it appeared that the files under package "jplag.java15.grammar" had been generated in a wrong folder (namely in a "src" subfolder of the jplag root folder).

With this new value of "outputDirectory" it seems to be OK.

Best regards.
