Description

Hi,

With the changes introduced by SUREFIRE-1302 I'm now experiencing a failure on Linux when the fork mode is enabled:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.20.1:test (default-test) on project foo: There are test failures.
[ERROR]
[ERROR] Please refer to /foo/target/surefire-reports for the individual test results.
[ERROR] Please refer to dump files (if any exist) [date]-jvmRun[N].dump, [date].dumpstream and [date]-jvmRun[N].dumpstream.
[ERROR] The forked VM terminated without properly saying goodbye. VM crash or System.exit called?

I traced the issue back to the PpidChecker class, the code assumes that /bin/ps or /usr/bin/ps exist but this isn't guaranteed (especially on trimmed down containers commonly used for continuous integration).

It would be nice to have a fallback mechanism when ps isn't available, or at least check its existence and display an explicit message stating that it must be installed.
