add SONAME - https://github.com/GrapheneOS/hardened_malloc/issues/86

use correct Section: libs rather than misc

compatiblity with dh_dwz / dwz - https://github.com/GrapheneOS/hardened_malloc/issues/85

move to sub folder /usr/lib/libhardened_malloc.so so lintian will not complain
about non-versioned shared objects and missing symlinks. That extra complexity
is not needed here since this lib aims to be compatible with what it replaces.

full path is now /usr/lib/libhardened_malloc.so/libhardened_malloc.so

deprecate no longer needed make_all_hook_post as this was improved in genmkfile
