[MESOS-1252]: Support ENV MAVEN_HOME on the build.

    The build now supports the `MAVEN_HOME` environment variable which is
    used to resolve the `mvn` executable. If no `MAVEN_HOME` is specified we
    will use the one available in the `PATH`.

Testing
-------

Success

1. Testing MAVEN_HOME without a `mvn` executable in your path.
1.1 Specify MAVEN_HOME=/path/to/your/maven/home `./configure`
1.2 Check src/Makefile and validate that the variables MAVEN_HOME and MVN point 
to the correct path.
1.3 See that `$(MVN)` is used instead of `mvn`.

2. With a `mvn` executable in your path.
2.1 Do not specify a MAVEN_HOME just make sure you have a `mvn` executable in 
your path and call `./configure`
2.2 Check src/Makefile and validate that the variables MAVEN_HOME is empty but 
the MVN point to the correct executable.
2.3 See that `$(MVN)` is used instead of `mvn`.


Failures
2. With a MAVEN_HOME that has a `bin/mvn` executable missing.
2.1 Call `MAVEN_HOME=/the/path ./configure`
2.2 you should get an error that tells that `mvn` is missing from 
"/the/path/bin".

2. Without a `mvn` executable in your path.
2.1 Call `./configure`
2.2 you should get an error that tells that `mvn` is missing.
