sstate.bbclass: make PV to depend on PV variable value 

Currently PV is defined in meta/conf/bitbake.conf as a python
expression: "${@bb.parse.BBHandler.vars_from_file(d.getVar('FILE',
False),d)[1] or '1.0'}". As FILE is whitelisted it causes PV to
not depend on it. This causes sstate code to not detect that
PV changes when recipe filename changes.

Making PV to explicitly depend on PV variable value overrides default
behaviour. Instead of depending on python expression bitbake depends
on evaluated value of PV variable, which should fix the above
mentioned issue.
