Subject: [PATCH] build.gradle: fix checkstyle plugin failure

The `checkstyle` plugin of Gradle fails in JDK11 and gives the error
below:

    Unable to create Root Module: config ...

The main reason is that, in JDK11, the `user.dir` cannot be reset by
Gradle [1]. So, checkstyle plugin is unable to locate the suppressions
file correctly.

Let's add `config_loc` variable suggested by Gradle to solve the
problem [1].
