bcc: move to the right dynamic-layer

* it depends not only on meta-oe, but on meta-python as well
  and because meta-python depends on meta-oe, we can enable this
  when ever meta-python is included

* fixes:

+Subject: [PATCH] CMakeLists.txt: override the PY_CMD_ESCAPED
+
+Override the PY_CMD_ESCAPED as the PY_CMD_ESCAPED is constructed by
+the full path of the python3. In some cases, the path is so long and
+result in the PY_CMD_ESCAPED exceeds 255 characters and comes below
