Ethan Zuo 8d9c5ceff4 kbuild: Fix permissions of modules.builtin.modinfo ...

[ Upstream commit 6d60354ea2 ]

Currently, modules.builtin.modinfo is created with executable permissions
(0755). This is because after commit 39cfd5b121 ("kbuild: extract
modules.builtin.modinfo from vmlinux.unstripped"), modules.builtin.modinfo
is extracted from vmlinux.unstripped using objcopy. When extracting
sections, objcopy inherits attributes from the source ELF file.

Since modules.builtin.modinfo is a data file and not an executable,
it should have regular file permissions (0644). The executable bit
can trigger warnings in Debian's Lintian tool.

Explicitly remove the executable bit after generation.
