Fix warnings due to missing attributes for __EI_ prefixed symbols

With new compiler (gcc >= 9 ?) building uClibc-ng now gives this sort of warnings:

./include/libc-symbols.h:426:25: warning: '__EI_localeconv' specifies less restrictive attribute than its target 'localeconv': 'nothrow' [-Wmissing-attributes]
  426 |  extern __typeof (name) __EI_##name __attribute__((alias (__hidden_asmname1 (,#local))))
      |                         ^~~~~
./include/libc-symbols.h:429:29: note: in expansion of macro '__hidden_ver1'
  429 | #  define hidden_def(name)  __hidden_ver1(__GI_##name, name, name);
      |                             ^~~~~~~~~~~~~
./include/libc-symbols.h:497:32: note: in expansion of macro 'hidden_def'
  497 | # define libc_hidden_def(name) hidden_def (name)
      |                                ^~~~~~~~~~

  306 | libc_hidden_def(localeconv)
      | ^~~~~~~~~~~~~~~
In file included from libc/misc/locale/localeconv.c:8:

  261 | struct lconv *localeconv(void)
      |               ^~~~~~~~~~

The fix is mostly being backported/adapted from glibc.
