Remove unused and upstreamed patch

This patch was initially used to fix a bunch of build failures with
GCC 6. The first hunk was for i386 and x86_64, while the second was for
ARM. See: https://bugzilla.redhat.com/show_bug.cgi?id=1307280

These have since been upstreamed.

The first hunk was actually not correct because it broke 4-colour RAWs
with VNG demosaic. So, it was eventually reverted in favour of a better
patch. See: https://github.com/LibRaw/LibRaw/issues/56

The second hunk was upstreamed as commit f4c0b98581a64147

No need to do a build just for this.
