adbd should be able to shutdown shell:unix_stream_socket
adbd started calling shutdown and waiting for EOF before closing
sockets in commit 74b7ec72, because closing a TCP socket while you have
pending data to read is specified to send a TCP RST to the other end,
which can result in data that we've written into the socket to be
prematurely thrown away on the other end. Not being able to do so on a
Unix domain socket is benign, aside from the denial showing up in the
log.
Fixes the following selinux denial when installing a package:
avc: denied { shutdown } for scontext=u:r:adbd:s0 tcontext=u:r:shell:s0 tclass=unix_stream_socket permissive=0
Test: manual
