[PATCH] headers_install: avoid those .install & ..install.cmd unused files

[Cheng Renquan <crquan@xxxxxxxxx>]

The modules_install, firmware_install, all install commands
don't generate such hidden unused files under destination;
I think headers_install also should not to generate such .install
& ..install.cmd files;
Usually, we call "make headers_install INSTALL_HDR_PATH=/some/path"
expecting it install just the header files, not those dot files;

The original "call if_changed" could generate ..install.cmd and
together with "touch .install" could make the 2nd time headers_install
quite faster but it's not meaningful here, because we usually only install once;
