classes/populate_sdk_ext: reset TCLIBCAPPEND to get consistent TMPDIR

populate_sdk_ext sets TMPDIR to a known static value with '/tmp' directory
name and that name is hard coded in a few places (e.g., in
meta-environment-extsdk.bb that writes the eSDK environment variables).

Distros that do not reset TCLIBCAPPEND (poky does) end up getting
TMPDIR = /tmp-${TCLIBCAPPEND} via defaultsetup.conf and that breaks
the functionality in eSDK that expects everything is in /tmp.

To get TMPDIR consistent, we also need to reset TCLIBCAPPEND in
populate_sdk_ext.bbclass.

Fixes: [YOCTO #11298]
