Introduce initial recipe for Softbus

Softbus implements "Distributed Communication Subsystem".
This commit provides initial recipe to build softbus
using bitbake and link it to the foundation application.

The functionality hasn't been tested (only build) so when
Softbus is actually used some missing bits may appear.

+Subject: [PATCH] Fix incorrect number of arguments to mq_open()
+
+Related issue:
+https://gitee.com/openharmony/communication_services_softbus_lite/issues/I2BBKX
+
+According to man:
+If O_CREAT is specified in oflag, then two additional arguments
+must be supplied.
+
+os_adapter.c is missing "mode" parameter in mq_open(). It will compile
+for MUSL, which does not check the number of arguments passed through
+variadic argument but it doesn't mean it works as designed.
+
+Fix this issue as well as build for other libraries with built-in
+checks by introducing missing "mode" argument.
+
+File mode has been selected to 0600 (RW for owner) but is a subject
+to change if needed.
