replacing "libcutils" with "libcutils_headers" can save the apex size
~356KiB (libbase.so + libcutils.so). clatd only needs the definition
AID_CLAT in the libcutils exported headers. It would be more
appropriate for using libcutils_headers.
before:
$ deapexer extract out/target/product/raven/system/apex/com.google.android.tethering.apex apex_with_clat_uses_libcutils
$ ls -all out/target/product/raven/system/apex/com.google.android.tethering.apex

after:
$ deapexer extract out/target/product/raven/system/apex/com.google.android.tethering.apex apex_with_clat_uses_libcutils_headers
$ ls -all out/target/product/raven/system/apex/com.google.android.tethering.apex

Both libbase.so and libcutils.so are removed from the apex
which is using clatd with libcutils_headers:
$ diff -r apex_with_clat_uses_libcutils apex_with_clat_uses_libcutils_headers
Only in apex_with_clat_uses_libcutils/lib64: libbase.so (263.4 kB)
Only in apex_with_clat_uses_libcutils/lib64: libcutils.so (91.0 kB)
