tools/patch: apply patch for EACCES on xattr copy
When compiling OpenWRT on a compressed btrfs volume the build fails in
libtool.
The file `libltdl/config/ltmain.m4sh` from `libtool-2.4.2.tar.xz` is
missing write permissions, therefore patch falls back to copying the
file and patching that. During this patch tries to preserve all file
attribute on the new copy.
However the attribute `btrfs.compression` is privileged and btrfs return
EACCES.
While patch ignores multiple other error codes during the copy of xattr
copy it is not prepared for EACCES and aborts.
EACCES should be ignored the same way as the other errors.
Build log:
