meta: remove True option to getVar and getVarFlag calls (again)

meta: remove True option to getVar and getVarFlag calls (again)

* True is default since 2016 and most layers were already updated
  not to pass this parameter where not necessary, e.g. oe-core was
  updated couple times, first in:
  https://git.openembedded.org/openembedded-core/commit/?id=7c552996597faaee2fbee185b250c0ee30ea3b5f

  Updated with the same regexp as later oe-core update:
  https://git.openembedded.org/openembedded-core/commit/?id=9f551d588693328e4d99d33be94f26684eafcaba

  with small modification to replace not only d.getVar, but also data.getVar as in e.g.:
  e.data.getVar('ERR_REPORT_USERNAME', True)

  and for getVarFlag:
  sed -e 's|\(d\.getVarFlag \?\)( \?\([^,()]*, \?[^,()]*\), \?True)|\1(\2)|g' \
      -i $(git grep -E 'getVarFlag ?\( ?([^,()]*), ?([^,()]*), ?True\)' \
          | cut -d':' -f1 \
          | sort -u)
