First move towards landlock support (#3). The shim is needed until
libc provides the proper wrappers for the landlock APIs; I hope it
doesn't take too long, but landlock was merged back in May and are
still missing.
This version includes two bugfixes:
- use ${MAKE} to recursively call make
- fix the misleading example in the man page: macros name may not be
reserved words
Both bugs found and fixed by Anna “CyberTailor”, thanks!
but still try to autodetect with pkg-config if they aren't provided.
Passing CFLAGS/LDFLAGS from the command line will still override the
guessed ones.
Calling `configure' with --disable-sandbox will disable the sandbox
support *completely* at compile time. gmid will still complain at
compile time and during the startup.
Users shouldn't disable the sandbox if possible, but instead report
problem upstream so they get fixed (hopefully.)

The actual implementation is based off doas' parse.y. This gave us
various benefits, like cleaner code, \ to break long lines, better
handling of quotes etc...
Include gmid.h as first header in every file, as it then includes
config.h (that defines _GNU_SOURCE for instance).
Fix also a warning about unsigned vs signed const char pointers in
openssl.
This adds a check for setproctitle and for the (linux) prctl
PR_SET_NAME. If setproctitle is not available, on linux we provide an
implementation that use prctl (taken from tmux compat layer.)
