buildenv.sh: clean up each tmpdir once
...instead of cleaning up the last one once for each tmpdir.
Commit 63e8d6321 changed the command registered atexit from
an explict "rm -rf '${DIR}'" to a call to a cleanup_tempdir
function, with the function containing the remove command.
As, however, the function name is not unique (in fact, it is
a constant), that function will get overridden at each invocation
of the tempdir function. The fact that the function is registered
several times with atexit doesn't help, as it will always remove
the last created temporary directory. Fix this, by creating function
names that encode the directory to be removed in the name. Fixes #1466.
