lbmk: don't handle TMPDIR directly

lbmk creates TMPDIR as /tmp/xbmk_*, but it's theoretically
possible that something could re-export it by mistake.

this change retains the same initialisation, but further
use is now via a new variable "xbmktmp", that stores the
value of TMPDIR upon lbmk's initialisation of it.

this reduces the chance of such a bug in the future, as
described above, so it is a preemptive/preventative fix.
