[modular] Fix race condition in PseudoDirServer

Sometimes, the child thread was calling .signal() even before parent
thread kicked off a .wait().

The fix is to use condition variables the correct way -- have the child
use use the lock :)

Test: Verified that it doesnt flake by running:
fx run-test peridot_tests -- --gtest_filter='ModularConfigReaderTest.OverrideConfigDir' --gtest_repeat=2000
