sm7125-common: add BROKEN_ENFORCE_SYSPROP_OWNER flag.

Quoting commit afc09932f6fa07c5f6beffbcdc2bb4691e527321 in
system/sepolicy [1]:

"Devices launching with R or eariler can this by setting following
under BoardConfig.mk"

It is impractical to replace every prop definition from qcom to
vendor_property_type for old platforms like SDM660, so relax the
enforcement to avoid triggering millions of neverallows.
