src: add support to pass flags to dlopen
* add constants for dlopen flags, which are needed
for dlopen's flag passing.
* introduce an optional parameter for process.dlopen(),
allowing to pass dlopen flags (using values from os.constants.dlopen).
If no flags are passed, the default behavior is to load the library
with RTLD_LAZY (perform lazy binding) and RTLD_LOCAL (symbols are
available only locally).
