Test ProcessBuilder.Redirect.INHERIT

This is similar to commit ed4aeadaac76089f2d3d3486e75fc8d3549929d0
which was rolled back because /proc/[mypid] is not accessible to
application / test processes (only to child processes) on Android
user builds by default.

The test now uses Os.fstat() to obtain the test process's
stdin/stdout/stderr inode numbers without access to /proc/. It
still relies on /proc/ for a child process, although that could
be replaced with a small C program if it causes trouble in the
future.

Test: cts-tradefed run cts -c libcore.java.lang.ProcessBuilderTest
