[LTP] [PATCH] run-posix-option-group-test.sh: Log and exit if one attempts to run tests without compiling

[shatur.linux@gmail.com]

From: Sharan Turlapati <sturlapati@vmware.com>

Currently, run-posix-option-group-test.sh erroneously
logs "***Tests Completed***" when no test has actually run if the script is invoked
to run without actually compiling the tests.

Check if the .run-test files actually exist before attempting to run them.
If not found, log a message indicating the problem and suggest to check if
the tests were compiled. Exit the script without attempting to run other
tests.
