Bug Description

In the wrapper scripts that get installed in /apps/bin, TMPDIR, TEMPDIR, and SNAP_APP_TMPDIR are all set to the same thing.

But in the eventual command that gets run, only TEMPDIR and SNAP_APP_TMPDIR still have that value. TMPDIR is empty and it shouldn't be.

Here's a tiny shell snap to reproduce. It just echos the various temp variables.

This appears to be because ubuntu-core-launcher runs strtok over the return value from getenv. strtok modifies the memory it is pointed at, and getenv returns the address in memory of the actual environment. Changing it, changes the environment.
