libpropertyinfoparser: only use system_shared_libs for bionic variant

libpropertyinfoparser is a dependency of libc, and so cannot use the
default system_shared_libs that includes libc.  It's not a dependency
of musl's libc though, and it needs to use musl's libc headers,
not the bionic libc headers provided by the libc_headers module.  Move
system_shared_libs and libc_headers into a target.bionic clause.
