Fix naming of test so it's printed properly

When run, I was seeing:
[ RUN      ] EGLTest.1
[       OK ] EGLTest.1 (11 ms)

That was because the test name I was using EGL_KHR_no_config_context,
matched an EGL enum and was being replaced.
This changes test name so it does not conflict with the EGL enum.
Test: adb shell /data/nativetest/EGL_test/EGL_test
