[PATCH v2 1/5] libtracefs: Fix issues with tracefs_option_id()

["Yordan Karadzhov (VMware)" <y.karadz@gmail.com>]

Few mistakes have been made when introducing this API function.
First of all, its declaration is missing from the header file.
In addition to this the argument type is missing "const".
