zephyr: Add _POSIX_C_SOURCE definition to fix build

Since version 3.6 of Zephyr, the _POSIX_C_SOURCE definition is required to be set per file to specify the version of the POSIX standard to be used. Define _POSIX_C_SOURCE to 200809L in the files that use strtok_r and strnlen. Signed-off-by: Mykyta Poturai <[email protected]>
