pbuilder: Use `printenv` instead of `set` to show environment variables

Bash and Dash show the output of `set` in a slightly different format
(for example `USER='foo'` vs `USER=foo`).  This confuses `diff` and causes
noise in the build log diffs.

Comparing the sorted output of `printenv` fixes this issue.

Using `printenv` has the additional advantage of showing only real
_environment_ variables (i.e. the set of variables that will be seen by
child processes) and no _shell_ variables (i.e. variables visible in the
shell but not exported to child processes like `PS1`).

Note: the full path is needed to prevent shells from using their
internal implementation of `printenv`.

(cherry picked from commit 0389d001456a64ebbb0f04627d00a6f077e7376c)
