QLockFile: Move the check for Linux /proc to a central place
I'll need it soon in QTemporaryFile. This also reduces the overhead,
since QFile::exists -> QFileInfo::exists needs to check if there's a
file engine that handles "/proc/version" (there isn't), convert the
UTF-16 filename to UTF-8 and QFileSystemEngine::fillMetaData will issue
a more expensive stat(2) syscall.
access(2) is cheaper.
This commit also introduces QT_LINUX_ALWAYS_HAVE_PROCFS that isn't
defined anywhere, but could be passed during configure with -D if a
build wants it.
