Take write lock on global provider in EvpKeyFactoryTest

We've recently seen some internal dry-run build failures, likely due to
increased concurrency on beefy internal build hosts (see [here][1] and
[here][2]). These failures manifested with this tell-tale signature:

```
  JUnit Jupiter:EvpKeyFactoryTest:ecPrivate(KeyPair, String, boolean):EC-521, Translate: false
    MethodSource [className = 'com.amazon.nativejcebindings.test.EvpKeyFactoryTest', methodName = 'ecPrivate', methodParameterTypes = 'java.security.KeyPair, java.lang.String, boolean']
    => org.opentest4j.AssertionFailedError: expected: <sun.security.ec.ECPrivateKeyImpl@ffff6867> but was: <com.amazon.nativejcebindings.EvpEcPrivateKey@ffff65db>
...
       com.amazon.nativejcebindings.test.EvpKeyFactoryTest.getSamples(EvpKeyFactoryTest.java:414)

```

So, we take a write lock on the global provider to ensure no other
concurrently executing test is polluting the EvpKeyFactoryTest's JVM
provider state.
