Joel Winarske aa32734876 capnproto: build position independent code ...

The recipe produces static archives only, and does not compile them PIC, so
linking capnp or kj into a shared library fails:

  libkj.a(exception.c++.o): relocation R_X86_64_TPOFF32 against
  `kj::(anonymous namespace)::threadLocalCallback' can not be used when making
  a shared object; local-exec is incompatible with -shared

kj/exception.c++ has a file-scope thread_local, which non-PIC code compiles to
the local-exec TLS model. A shared object cannot use that model, so the link
fails on any consumer that puts capnp inside a .so. Debian and Fedora do not
hit this because they ship shared libcapnp.

Set CMAKE_POSITION_INDEPENDENT_CODE. Packaging is unchanged: still static,
still no .so, no new packages and no ABI surface, only the code model differs.

Backport of the same change sent for master, where the recipe is 1.5.0.
