build: Create .la library for leveldb

Libtool will yell at you if you try to link a shared library against
static ones.

This change creates a libtool archive library for leveldb and allows a
shared library to be linked against it portably.

Also specify -static in both:

- ..._la_CXXFLAGS so that libtool will avoid building two versions of
  each object (one PIC, one non-PIC). We just need the one that is
  suitable for static linking.
- ..._la_LDFLAGS so that libtool will create a static library.

If we don't specify this, then libtool will build two versions of each
object and prefer the non-static PIC version of the object, which is
built with -DDLL_EXPORT -DPIC for mingw-w64 targets. This can cause
symbol resolution problems when we link this library against an
executable that does specify -all-static, since that will be built
without the -DDLL_EXPORT flag.

This is especially important for leveldb and memenv since they link
against libwinpthreads, which has difference symbols depending on
whether DLL_EXPORT is defined or not.

[META] This change is done in preparation for a future commit where we
       link the libbitcoinkernel library against this one.

Appendix:

The specific linker errors when linking memenv built without -all-static
against a bitcoind with -all-static look like:
