scripts: objdiff: get the path to .tmp_objdiff more simply
This commit is a minor refactoring.
Temporary files for objdiff are stored in .tmp_objdiff directory
which is located at the top directory.
To get the path to this directory,
SRCTREE=`git rev-parse --show-toplevel`
TMPD=$SRCTREE/.tmp_objdiff
seems easier to understand than
GIT_DIR=`git rev-parse --git-dir`
TMPD=${GIT_DIR%git}tmp_objdiff
Besides, it is not always necessary to create .tmp_objdiff dicrectory.
It should be created only for "record" command.
