plugins do have unresolved symbols. so exclude them from
dpkg-shlibdeps's scan list. this silences warnings like:
```
dpkg-shlibdeps: warning:
debian/ceph-base/usr/lib/ceph/erasure-code/libec_shec_generic.so.1.0.0
contains an unresolvable reference to symbol
_ZN4ceph6buffer3ptrC1EPNS0_3rawE: it's probably a plugin
```
