kbuild: Fix permissions of modules.builtin.modinfo
[ Upstream commit 6d60354ea2f90352b22039ed8371c4f4321df90e ]
Currently, modules.builtin.modinfo is created with executable permissions
(0755). This is because after commit 39cfd5b12160 ("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.
Fixes: 39cfd5b12160 ("kbuild: extract modules.builtin.modinfo from vmlinux.unstripped")
