List of builtin commands incorrectly includes hash

[krader1961]

The hash "command" is actually an alias:

ast/src/cmd/ksh93/data/aliases.c

Line 38 in 75f9c39

{"hash", NV_NOFREE, "alias -t --"},

Yet is also is defined as a distinct builtin command:

ast/src/cmd/ksh93/data/builtins.c

Line 71 in 75f9c39

{"hash", NV_BLTIN | BLT_SPC | BLT_DCL, bltin(alias)},

This is absurd. Even if the alias was removed the builtin of the same name would not work as expected.
