[LTP] [PATCH v4] include/Makefile: Fix cleaning targets

[Ricardo B. Marlière]

From: Ricardo B. Marlière <rbm@suse.com>

Add ac-clean target as dependency of ac-maintainer-clean and add missing
files to the removal list. This way the project top level Makefile cleaning
targets can make use of it. Also, add "compile" to the AUTOMAKE_FILES
list and move stamp-h1 to where it's actually created: within include/
directory.

Fixes: 817d8095fbfe ("Rename linux_syscall_numbers.h to lapi/syscalls.h")
Reviewed-by: Petr Vorel <pvorel@suse.cz>

Changes in v4:
- Defined $CLEAN_SUBDIRS
- Fixed git commit message
- Link to v3: https://lore.kernel.org/r/20250409-fix_make_clean-v3-0-a33a84b2be05@suse.com

Changes in v3:
- Added "include" dir to existing for loop instead of adding a new $(MAKE)
  directive.
- Added it also to `make distclean` target.
- Link to v2: https://lore.kernel.org/r/20250408-fix_make_clean-v2-0-48f93c3dd0bf@suse.com

Changes in v2:
- Dropped the commit that added files to ac-maintainer-clean target
	(They're already in AUTOMAKE_FILES, thanks P. Vorel!)
- Added "compile" file to the AUTOMAKE_FILES list
- Added missing call to include/Makefile to ac-maintainer-clean target
- Link to v1: https://lore.kernel.org/r/20250327-fix_make_clean-v1-0-8b9ed2a8d96a@suse.com

NOTE: The "compile" file is added during the autotools target:
$ make autotools
<snip>
configure.ac:26: installing './compile'
configure.ac:24: installing './config.guess'
configure.ac:24: installing './config.sub'
configure.ac:7: installing './install-sh'
configure.ac:7: installing './missing'
<snip>
