Make add-face-text-property not be destructive on strings

* src/textprop.c (add_properties): Take a parameter to say whether
it's allowed to be destructive or not (bug#20153).
(add_text_properties_1): Ditto.
(Fadd_face_text_property): Use this to say that it shouldn't
modify face properties on strings destructively.  This avoids
altering the face properties of one string when altering them on a
copy of the string.
