UST is doing the right thing here. The error arises as access to the
shared memory segment is mediated by AppArmor. For that, we should strip
all lttng tracepoints from production builds for QtUbuntu and the
Platform API.

Title:
  liblttng-ust0 Error opening shm /lttng-ust-wait-5

Status in Platform API:
  New
Status in QT Ubuntu:
  New
Status in ust package in Ubuntu:
  Confirmed

Bug description:
  Confined apps don't have access to this and continuously produce this
  error message in stderr:

  libust[31283/31285]: Error: Error opening shm /lttng-ust-wait-5 (in
  get_wait_shm() at lttng-ust-comm.c:958)

  
  This is printed to the application's log about once every other second and makes it hard to read the application's own debug output. For a better app developer experience this message should be silenced.
