bitbake: fetch: copy files with -H

When using a PREMIRROR with plain (non-unpack) files, a SRC_URI like

SRC_URI = "file://devmem2.c"

will cause devmem2.c to be a symlink in the WORKDIR pointing to the
local PREMIRROR.

Trying to apply a patch on this file will either modify the file on
the PREMIRROR or will fail due to sanity checks:

ERROR: devmem2-1.0-r7 do_patch: Command Error: 'quilt --quiltrc /cache/build-ubuntu/sysroots/x86_64-oe-linux/etc/quiltrc push' exited with 1  Output:
Applying patch devmem2-fixups-2.patch
File devmem2.c is not a regular file -- refusing to patch
