installd: Skip profile preparation if primary.prof does not exist

If the primary.prof does not exist in .dm file, the profman here will
create an empty reference profile, which will slow down the dex2oat.

And, the profman process is expensive (about hundreds of
milliseconds), we should avoid it if the primary.prof does not exist.
