bp2build: allowlist //external/libcap/...

Browse Source 
This builds cap_names.list.h, which uses an eponymous filegroup
"generate_cap_names_list.awk" in Soong, but uses the file target
directly in Bazel.

This also improve filegroup support for mixed builds, by issuing a
cquery call _without_ arch. Filegroups in Soong don't have configurable
properties, so don't generate Bazel filegroups into buildroot's
config_nodes (which was x86_64 by default).

The mixed_build_root now looks like this:

```
config_node(...)
config_node(...)
config_node(...)
config_node(...)

...

    srcs = ["@//bionic/linker:linker_sources_x86",
