selftest: devtool: set BB_HASHSERVE_UPSTREAM when setting SSTATE_MIRROR

* with my build/conf/local.conf:
  SSTATE_DIR = "/OE/build/poky/build/sstate-cache"
  these devtool tests will first set own SSTATE_DIR and the original one set as SSTATE_MIRROR:

2023-03-11 11:51:46,837 - oe-selftest - INFO - test_devtool_update_recipe_append (devtool.DevtoolUpdateTests.test_devtool_update_recipe_append)
2023-03-11 11:51:46,846 - oe-selftest - DEBUG - Appending to: /OE/build/poky/build/build-st-2023-03-11-patch2/devtool.DevtoolUpdateTests.test_devtool_update_recipe_append/build-st/conf/selftest.inc
SSTATE_DIR = "/OE/build/poky/build/build-st-2023-03-11-patch2/devtool.DevtoolUpdateTests.test_devtool_update_recipe_append/build-st/sstate_devtool"
SSTATE_MIRRORS += "file://.* file:////OE/build/poky/build/sstate-cache/PATH"

* but that unfortunately leads to a warning from sanity.bbclass
  about SSTATE_MIRRORS without matching BB_HASHSERVE, because
  BB_HASHSERVE is set to "auto" by default

  these tests failing with:

* just setting BB_HASHSERVE to empty doesn't work, because then we
  would need to disable OEEquivHash as well as it fails with:

  ERROR: OEEquivHash requires BB_HASHSERVE to be set
