dim: fix From: matching in apply patch
I occasionally bounce patches to intel-gfx@ to get CI for patches that were only sent to dri-devel@ or were caught in the moderation queue. This results in a Resent-From: header being added.
Applying such a patch leads to the From: match in apply_patch() to match Resent-From: rather than the actual From:. If whoever bounced the patch is also applying the patch, their Signed-off-by won't be automatically added.
Match From: from the beginning of the line to fix this.
