Since presym is now mandatory, mruby.h includes presym.h so that
MRB_SYM() macros are available everywhere without explicit include.
Remove redundant #include <mruby/presym.h> from all source files.

rename mrb_alloca() to mrb_temp_alloc() for clearer naming - the new name
better describes its purpose as GC-managed temporary allocation. keep
mrb_alloca() as a macro alias for backward compatibility.
apply mrb_temp_alloc() to fix potential memory leaks in:
- mruby-strftime: if mrb_str_cat() raises, allocated buffers now cleaned by GC
- mruby-io File.readlink: if mrb_str_new() raises, buffer now cleaned by GC
