[Buildroot] [PATCH 2/2] mongoose: optionally provide shared library

mongoose package can provide a webserver and, optionally, a shared
library: this is what Centos, among other distros, is doing.

It's now possible to include in the build both the mongoose executable
and libmongoose.so

Not too sure how should be handled the situation where mongoose is
select and neither the webserver nor libmongoose.so are not selected

I'd also appreciate some feedback on the shared library compilation
flags

regards,
Davide
