Tests: fix: select_poll_epoll: test assumes epoll fd value

The test currently assumes that epoll fds are always == 3, which
is not always the case depending on the execution environment.

This change causes `select_poll_epoll` to produce a JSON file
containing the application's pid and epoll fd values that is
then used by the validation script.

Note that the test is converted to C++ to allow the use of
internal utils (common/error.h/cpp) without changing their linkage.

However, the code is still regular C to ease the backport of this
fix.
