ESoupAuthBearer: Is not thread safe
Moving this from a downstream bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1810592
The backtrace of the crash there shows two threads calling e_soup_auth_bearer_set_access_token()
at the same time, causing use-after-free in one of those threads.
A solution is to make ESoupAuthBearer thread safe.
