lib/nettle/int/nettle-internal.h: include alloca.h if configure found it

Needed for alloca definition on Solaris, to avoid build error with gcc 14:

lib/nettle/int/nettle-internal.h:59:39: error: implicit declaration of
 function 'alloca' [-Wimplicit-function-declaration]
   59 | #define TMP_ALLOC(name, size) (name = alloca(sizeof(*name) * (size)))
      |                                       ^~~~~~

Closes #782
