[Buildroot] [git commit branch/2018.11.x] leveldb: install memenv static library and header

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=29cedb230b2022c1c9339cd807907f6b0818c9aa
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.11.x

The project builds a tiny static library that consists of a single
symbol which creates an in-memory LevelDB database.

That library is not installed by default and may be used by other
projects.

This commit installs in the staging directory the libmemenv.a static
library and the memenv.h header file.
