build: add systemtap's sys/sdt.h as depends
The sys/sdt.h header is required to build Bitcoin Core with Userspace
Statically Defined Tracing support. Systemtap version 4.5 (May 2021)
is used as the most recent version 4.6 (Nov 2021) fails to build.
See e.g. https://sourceware.org/git/?p=systemtap.git;a=commit;h=1d3653936fc1fd13135a723a27e6c7e959793ad0
As Systemtap itself is not needed, the build steps (configure and
make) are skipped. We require fewer build dependecies and don't
waste time building depends we don't end up using. However, the
configure step would normally processes sys/sdt-config.h.in. The
resulting sdt-config.h defines _SDT_ASM_SECTION_AUTOGROUP_SUPPORT
(either 0 or 1 to indicate whether the assembler supports "?" in
.pushsection directives). For now, we assume all currently used
assemblers supports this feature and remove the check from the
sys/sdt.h header file in a patch.
