scripts/oe-setup-builddir: Keep track of TEMPLATECONF setting
Keeping track of the TEMPLATECONF variable in the build
tree will let this script produce the same output when
listing 'conf-notes.txt' every time the script is run,
regardless of whether or not TEMPLATECONF has been
provided by the user.
Note that the default value for TEMPLATECONF now comes from
an easily customizable file $OEROOT/.templateconf
