Buffers creation - creates shared memory for the tracing buffers.

Ressource accounting, preventing abuses, is easier if the traced
application via libust does the buffer creation!
The main reason was because the application cannot set the shared
memory with the read access to the tracing group. (unless the apps
uid is in the tracing group).
I'm not quite with you here... Shouldn't all apps that we want to
trace have to be in the tracing group? Or is this unreasonable...
I think having a policy where all users who need to trace are members
of the tracing group as are all applications that can be traced makes
a lot of sense....
