[poky] [PATCH 1/5] poky.conf: add more hash whitelist

[Kevin Tian]

DATE are referenced by patch_do_patch
TIME are referenced by do_distro_check/do_checkpkg
BBPATH/THISDIR/OEROOT/_ impacts the scenario when using different source path.
(OEROOT are brought in as a shell variable, included as dependency of shell tasks)
DL_DIR/SSTATE_DIR are listed as dependency too, by pstaging_fetch

Some tasks may not contribute to sstate packages, e.g. do_checkpkg. But for
safety all of them are whitelist this time.

How to handle preserved shell variables is still in progress, which contributes to
another large set of volatile dependencies bound to build system
