    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.
