Simplify mvn.py invocation

mvn.py is resolved relative to external package of Bazel project.
Simplify invocation for the callers of this utility, by prefixing
the utility with environment variable: OUTPUT_BASE.

The callers can use it:

  export OUTPUT_BASE=`bazel info output_base`
  ./bazel-genfiles/tools/maven/api_install.sh

where api_install.sh is a script generated by package.bzl Skylark rule.

Also replace py_binary with exports_files, because py_binary rule
wasn't actually used.
