Current test will fail in the case when the target process exits before
process_mrelease is called. However this is possible and should not be
treated as an invalid case. Add special handling of this case in the
test.

Increase the allocation step to 5MB and decrease the delay between
allocations to 200ms in order to speed up memory consumption and
avoid the test timing out.

Since lmkd tests require time to build up memory pressure, they cause
timeouts when run as part of presubmits. Move them into the
presubmit-large category with higher timeout to prevent such failures.

Add a test to verify a process killed by lmkd is being reaped when
kernel supports process_mrelease syscall.

Memory cgroups are disabled on non-AndroidGo devices. Change the test
not to fail due to missing in-kernel memory cgroup support.

We introduced supporting process type while
registering a process in lmkd. Thus we need
to set process type when registering the test
unit or lmkd would not be able to kill it.

This change is to align how we get proc_name
between lmkd and lmkd_unit_test or it will always
fail when we run command such as ./lmkd_unit_test
under the device shell.

lmkd's test depends on the socket_local_client() function from
libcutils, but since liblog also exposes this symbol weakly, that is
the symbol that gets used instead of the intended libcutil's copy of
the symbol.
Test: build

Excessive number of failed kill reports when lmkd can't find an eligible
process to kill or frees not enough memory pollutes logs and bugreports.
Cleanup kill reports to remove duplicate information and rate limit failed
kill attempts at 1 report per sec. The number of suppressed failed kills
will be reported in the next lmkd report.

lmkd_unit_test gets an selinux violation when run unprivileged:
lmkd_unit_test: type=1400 audit(0.0:???): avc: denied { search } for
name="lowmemorykiller" dev="sysfs" ino=??? scontext=u:r:shell:s0
tcontext=u:object_r:sysfs_lowmemorykiller:s0 tclass=dir
permissive=0
resulting in log noise. Check for INKERNEL_MINFREE_PATH existence
after known to be escalated as root user to suppress noise.
Test: lmkd_unit_test as unprivileged user, there should be no audits.

This change allows lmkd-test to work correctly when it's started
using absolute as well as relative path.
