Disable hwasan memory stats.

Disable a debugging feature in hwasan that seems to be causing flaky selinux
denials in the boot test:

05-02 12:11:11.360  1663  1663 I auditd  : type=1400 audit(0.0:8): avc: denied { read } for comm="iptables-wrappe" path="/proc/1015/statm" dev="proc" ino=30968 scontext=u:r:netutils_wrapper:s0 tcontext=u:r:netmgrd:s0 tclass=file permissive=0

I could not reproduce this locally, but this feature has no users and
I've verified that things keep working without it.

This does not affect any shipped product.
