Implement masking in FileType hashing on Unix

Browse Source 
Commit 77005950f09d2f9ba54962bf5adc3f2bc3a7213f implemented masking of
FileType to fix an issue[^1] in the semantic of FileType comparison.
This commit introduces masking to Hash to maintain the invariant that
x == y => hash(x) == hash(y).
