Adin Scannell 0e2f1b7abd Update package locations. 
Because the abi will depend on the core types for marshalling (usermem,
context, safemem, safecopy), these need to be flattened from the sentry
directory. These packages contain no sentry-specific details.

Fabricio Voznika 3dd3275da7 Add more files to /proc/[pid]/* 
Files not implemented require VFSv2 plumbing into the kernel.
Also, cgroup is not implemented yet.

Michael Pratt df5d377521 Remove go_test from go_stateify and go_marshal 
They are no-ops, so the standard rule works fine.

Ayush Ranjan 661b2b9f69 procfs: Migrate seqfile implementations. 
Migrates all (except 3) seqfile implementations to the vfs.DynamicBytesSource
interface. There should not be any change in functionality due to this migration
itself.

Please note that the following seqfile implementations have not been migrated:
- /proc/filesystems in proc/filesystems.go
- /proc/[pid]/mountinfo in proc/mounts.go
- /proc/[pid]/mounts in proc/mounts.go
This is because these depend on pending changes in /pkg/senty/vfs.
