[PATCHv2 1/2] Documentation/kbuild/headers_install.txt: remove obsolete instructions

[Yann Droneaud]

As noted by Sam Ravnborg in reply [1] to "[PATCHv1 2/2]
Documentation/kbuild/headers_install.txt: update documentation" [2],
all architectures support exporting userspace headers (while 'um'
being a special case), so there's no need to list them.

This patch removes the obsolete shell commands to list
architectures with a dedicated 'asm' directory.
