Writing the profile to /etc/apparmor.d, while also manually loading it
into the kernel results in quite a bit of confusion. In addition, it
means that people using apparmor but have /etc mounted read-only cannot
use apparmor at all on a Docker host.
Fix this by writing the profile to a temporary directory and deleting it
after it's been inserted.

In order to check that we can have the `ptrace` rule, we need to
actually calculate the version of apparmor_parser.

ExecPath isn't used by anything, and the signal apparmor rule isn't used
because it refers to a peer that we don't ship.

This change centralizes the template manipulation in a single package
and adds basic string functions to their execution.

Ubuntu ships apparmor_parser 2.9 erroniously as "2.8.95". Fix the
incorrect version check for >=2.8, when in fact 2.8 deosn't support the
required feature.

Using {{if major}}{{if minor}} doesn't work as expected when the major
version changes. In addition, this didn't support patch levels (which is
necessary in some cases when distributions ship apparmor weirdly).
