QProcessPrivate::startProcess - fix invalid encodedProgramName (OS X)

CFBundleCopyExecutableURL returns different URLs (can be absolute or relative)
for the same bundle (caching) - and this results in an
invalid encodedProgramName (in case we try to start the same process twice),
for example, if we start: QProcess p; p.start("nestedDir/nested.app")
twice, the second time we'll have an error trying to start something like
nestedDir/nested.app/_and_here_absolute_url.
