Snap package of bitcoind lacks apparmor access to entropy files in proc

[BrunswickBTC]

Apparmor triggers syslog messages when bitcoind attempts to access certain files in /proc
In bitcoind source the following list of files appear to be accessed for entropy collection:
AddFile(hasher, "/proc/diskstats");
AddFile(hasher, "/proc/vmstat");
AddFile(hasher, "/proc/schedstat");
AddFile(hasher, "/proc/zoneinfo");
AddFile(hasher, "/proc/meminfo");
AddFile(hasher, "/proc/softirqs");
AddFile(hasher, "/proc/stat");
AddFile(hasher, "/proc/self/schedstat");
AddFile(hasher, "/proc/self/status");

Snap's apparmor settings for the bitcoin-core package should be updated to permit access to these files.
