ext/session: pass ini options to extra processes in tests

[mikhainin]

The change and the problem are similar to #11004.

When we build with --enable-session=shared, the tests are running with -d session.so but as long as we don't pass this argument to the inner process, it will fail with undefined function session_start().

It seems like this broke the build on Windows... Is there a way to take a look at the failure?

Interestingly, the failure looks like this:

     *** Testing session_regenerate_id() : basic functionality for cookie ***
002- string(%d) "X-Powered-By: PHP/%d.%d.%s
002+ string(698) "
003+ Warning: PHP Startup: Unable to load dynamic library 'mysqli' (tried: C:\php\ext\mysqli (The specified module could not be found), C:\php\ext\php_mysqli.dll (The specified module could not be found)) in Unknown on line 0

I also removed -n argument, we need to somehow pass the extension directory. The script that runs the test gets this directory from ini-file and if the inner process doesn't read the config, it cannot find what we passed in the -d extension=...

Great! Thanks @negram!
