[PATCH RESEND] cocci: avoid self-references in object_id transformations

[René Scharfe]

The object_id functions oid_to_hex, oid_to_hex_r, oidclr, oidcmp, and
oidcpy are defined as wrappers of their legacy counterparts sha1_to_hex,
sha1_to_hex_r, hashclr, hashcmp, and hashcpy, respectively.  Make sure
that the Coccinelle transformations for converting legacy function calls
are not applied to these wrappers themselves, which would result in
tautological declarations.
