Extract errno value_strings from usb code

The convention of returning negative errno codes from the Linux kernel
is not just limited to usb/usbip, it is also needed by netlink. Now
netlink error codes are properly dissected.

Also add ERFKILL and EHWPOISON (since 2009 and 2011) and change ESTALE
and ENOSYS to match the current description as of Linux 4.7. Fixed
header paths in comments too.

Used this command to generate the table (with fixups for gaps):

    cpp -dM -CC include/uapi/asm-generic/errno.h |
    perl -ne '/^#define (E[A-Z0-9]+) ([0-9]+) \/\* (.+) \*\// &&
    printf "    { -%-4s \"%s (-%s)\" },\n", "$2,", $3, $1' | sort -k2
