ANDROID: pidfd: Disable FS_PID

Browse Source 
Commit cb12fd8e0d ("pidfd: add pidfs") introduced a change to "move
pidfds from the anonymous inode infrastructure to a tiny pseudo
filesystem".  This causes many x86 pre-submit tests to fail.

The commit message goes on to say:

"The code is entirely optional and fairly small. If it's not selected we
 fallback to anonymous inodes. Heavily inspired by nsfs which uses a
 similar stashing mechanism just for namespaces."

So let's try to simply disable it and see that brings our tests back
to a state of passing.
