fix undesired compilation error(s) of feature test
If don't fix, the feature test will generate undesired .h which will be used in later compilation, some will cause build failed. see *.h{1,2} for details, run following cmd to see difference: diff -uprN <(more *.h1|sed 's:\.h1$:.h:g') <(more *.h2|sed 's:\.h2$:.h:g') found by using clang 18 with CFLAGS: -Wall link of debian's patches is: https://salsa.debian.org/debian/runit/-/tree/master/debian/patches 0029-fix-ftbfs-with-gcc14.patch chkshsgr.c trycpp.c trypoll.c tryshsgr.c tryulong64.c: error: call to undeclared function '...'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] functions are: _exit, exit, getgroups, printf, setgroups tryflock.c trysgact.c trysgprm.c trywaitp.c: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]
