Write all BUILD files for queryview

Some BUILD files cannot be written to support bp2build as they already
exist in the tree; however, all BUILD files should be written for
queryview as they are not intended to coexist with handwritten BUILD
files.

Test: $ bazel query --config=queryview
  "somepath(//system/linkerconfig:linkerconfig--android_arm64_armv8-a ,
  //bionic/libc:libc_openbsd--android_arm64_armv8-a_static)"
Test: build/bazel/ci/bp2build.sh
