Fernflower, Mergetool and Renametool don't apply jvmargs

[Marcono1234]

The following jars allow specifying jvmargs in the config.json file, but do not apply them when running the task. Especially for fernflower this might be rather important.

• Fernflower
• Mergetool
• Renametool

This could probably be solved by adding jvmArgs <config>.jvmargs to the respective taks, for example

task renameClient(type: RemapJar, dependsOn: [downloadRenameTool, downloadLibraries, filterClient]) {
    jar downloadRenameTool.dest
    // Use jvmargs
    jvmArgs RENAMETOOL.jvmargs
    input filterClient.archivePath
    mappings file(PATH_VERSION + 'joined.tsrg')
    args RENAMETOOL.args
    dest file(PATH_CACHED_VERSION + project.version + '.client.mapped.jar')
}
