musl: remove compat basename declaration and add RLIMIT_RTTIME define

This declaration was added to musl to avoid warnings for applications that
expect GNU basename() in string.h.

Pre-ansi style declarations were used to avoid causing errors due to
incompatibile declarations of basename().

In C23, just like in C++, function declarations with no arguments are treated
as having no arguments, instead of having unspecified arguments. As such,
this creates a conflicting declaration in C23.

+Subject: [PATCH] remove non-prototype declaration of basename from string.h
+
+commit 37bb3cce4598c19288628e675eaf1cda6e96958f suppressed the
+declaration for C++, where it is wrongly interpreted as declaring the
+function as taking no arguments. with C23 removing non-prototype
+declarations, that problem is now also relevant to C.
+
+the non-prototype declaration for basename originates with commit
+06aec8d7152dfb8360cb7ed9b3d7215ca0b0b500, where it was designed to
+avoid conflicts with programs which declare basename with the GNU
+signature taking const char *. that change was probably misguided, as
+it represents not only misaligned expectations with the caller, but
+also undefined behavior (calling a function that's been declared with
+the wrong type).
+
+we could opt to fix the declaration, but since glibc, with the
+gratuitously incompatible GNU-basename function, seems to be the only
+implementation that declares it in string.h, it seems better to just
+remove the declaration. this provides some warning if applications are
+being built expecting the GNU behavior but not getting it. if we
+declared it here, it would only produce a warning if the caller also
+declares it themselves (rare) or if the caller attempts to pass a
+const-qualified pointer.
