Make gitrev more reliable

Browse source 
In some build methods, the gitrev is unnecessarily set to "unknown".
We can improve this by changing the gitrev to use
`git describe --always --long --dirty`.

This gets the revision even when no tag matches (--always).  It prints
the hash even when it exactly matches a tag (--long).  And if there are
uncommitted changes, it appends "-dirty", rather than failing (--dirty).
