Currently an out-of-tree build does not work with read-only source directory because zfs_gitrev.h can't be created. Move this file to the build directory, which is more appropriate for a generated file, and drop the dist-hook for zfs_gitrev.h. There is no need to distribute this file since it will be regenerated as part of the compilation in any case. scripts/make_gitrev.sh tries to avoid updating zfs_gitrev.h if there has been no change, however this doesn't cover the case when the source directory is not in git: in that case zfs_gitrev.h gets overwritten even though it's always "unknown". Simplify the logic to always write out a new version of zfs_gitrev.h, compare against the old and overwrite only if different. This is now simple enough to just include in the Makefile, so drop the script.
