leveldb.Open does not work on Solaris

I built 8c09ded0e4ad and attempting to create/open a persistent LevelDB using 
leveled.Open(dirname, nil) fails with an error message complaining that file 
locking is not implemented in solaris. The issue is the build constraints in 
leveldb/db/file_lock_unix.go and leveldb/db/file_lock_generic.go do not include 
Solaris/Illumos (which is supported as of Go 1.3).

The fix is:

diff -r 8c09ded0e4ad leveldb/db/file_lock_generic.go
