umurmur: update to version 0.3.1

umurmur: update to version 0.3.1

Makefile changes
----------------

1. The location of uMurmur binary was changed to /sbin
in release 0.3.1. See release notes [1]

2. I need to specify location of the library file instead of
the directory.

Fixes:
CMake Warning at src/CMakeLists.txt:44 (target_link_libraries):
  Target "umurmurd" requests linking to directory
  "/build/staging_dir/target-powerpc_8548_musl/usr/lib".
  Targets may link only to libraries.  CMake is dropping the item.

Because of these two warnings, the build fails with
undefined references to
protobuf-c symbols (e.g. protobuf_c_message_get_packed_size).

Patches
-------

Removed all of them, because they are included in
the upstream source code.
