src/api.c: potential null ptr deref in cg_get_cgroups_from_proc_cgroups

In function cg_get_cgroups_from_proc_cgroups there is an allocation of memory by calling
malloc(buff_len).
Result of this allocation is not checked,
and in case of OOM it'll lead to null ptr deref.

This commit adds handling of possible null ptr as a result of failed
memory allocation.
