tools/include/uapi/asm/errno.h currently attempts to include
non-existent arch-specific errno.h header for xtensa.
Remove this case so that <asm-generic/errno.h> is used instead,
and add the missing arch-specific header for parisc.

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.

This is currently working due to extra include paths in the build.
Committer testing:
$ cd tools/include/uapi/asm/
Before this patch:
$ ls -la ../../arch/x86/include/uapi/asm/errno.h
ls: cannot access '../../arch/x86/include/uapi/asm/errno.h': No such file or directory
$
After this patch;
$ ls -la ../../../arch/x86/include/uapi/asm/errno.h
-rw-rw-r--. 1 acme acme 31 Feb 20 12:42 ../../../arch/x86/include/uapi/asm/errno.h
$
Check that that is still under tools/, i.e. hasn't escaped into the main
kernel sources:
$ cd ../../../arch/x86/include/uapi/asm/
$ pwd
/home/acme/git/perf/tools/arch/x86/include/uapi/asm

The BPF selftests fail to build with missing headers
'asm/bitsperlong.h' and 'asm/errno.h'.
These already exist in 'tools/arch/[arch]/include';
add architecture-agnostic header files in 'tools/include/uapi'
to reference them.
