Subject: ia64: tools: remove inclusion of ia64-specific version of errno.h header

There is no longer an ia64-specific version of the errno.h header below
arch/ia64/include/uapi/asm/, so trying to build tools/bpf fails with:

  CC       /usr/src/linux/tools/bpf/bpftool/btf_dumper.o
In file included from /usr/src/linux/tools/include/linux/err.h:8,
                 from btf_dumper.c:11:
/usr/src/linux/tools/include/uapi/asm/errno.h:13:10: fatal error: ../../../arch/ia64/include/uapi/asm/errno.h: No such file or directory
   13 | #include "../../../arch/ia64/include/uapi/asm/errno.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Thus, just remove the inclusion of the ia64-specific errno.h so that
the build will use the generic errno.h header on this target which was
used there anyway as the ia64-specific errno.h was just a wrapper for
the generic header.
