[ptxdist] [PATCH] kernel: fix modules.builtin.modinfo being executable

[Fabian Pfitzner]

Since kernel commit a26a6c93edfe ("kbuild: Strip trailing padding bytes from
modules.builtin.modinfo") [1], the resulting modules.builtin.modinfo file gets
copied by objcopy resulting in an executable file.

It seems, that objcopy detects this file as executable even though
the file is not executable at all.

Fix this problem by removing the execution bit afterwards.

I also send a patch upstream to the kernel [2].
