Re-opening for oxide as it turns out APP_PKGNAME is not an environment
variable that is being set anywhere for click apps. According to
https://developer.ubuntu.com/en/phone/platform/guides/app-confinement/,
its value can be inferred like this:

  APP_PKGNAME = APP_ID.split('_')[0]

Title:
  oxide should use an app-specific path for shared memory files

Status in Canonical System Image:
  In Progress
Status in Oxide:
  Confirmed
Status in webapps-sprint:
  Fix Committed
Status in apparmor-easyprof-ubuntu package in Ubuntu:
  Confirmed

Bug description:
  Oxide creates shared memory files as /run/shm/.org.chromium.Chromium.*. This results in an AppArmor rule like the following:
    owner /run/shm/.org.chromium.Chromium.* rwk, 

  But this rule is too lenient because a malicious app could enumerate
  these files and attack shared memory of other applications. Therefore,
  these paths need to be made application specific.
