lmdb: only set SONAME on the shared library

Setting soname in LDFLAGS means that the extra mdb tools also
incorrectly get soname set.  This then triggers package.bbclass to add a
duplicate shlib_provider in /usr/bin for liblmdb.so.0.9.29.  Then any
other recipe depending on liblmdb is going to get a 'Multiple shlib
provider' error.

shlibs2/lmdb.list before:
    liblmdb.so.0.9.29:/usr/bin:0.9.29
    liblmdb.so.0.9.29:/usr/lib:0.9.29

shlibs2/lmdb.list after:
    liblmdb.so.0.9.29:/usr/lib:0.9.29
