alloc_tag: Tighten file permissions on /proc/allocinfo
The /proc/allocinfo file exposes a tremendous about of information about
kernel build details, memory allocations (obviously), and potentially even
image layout (due to ordering). As this is intended to be consumed by
system owners (like /proc/slabinfo), use the same file permissions as
there: 0400.
