vasnwprintf: Fix test failures on musl libc.
* m4/vasnprintf.m4 (gl_PREREQ_VASNWPRINTF): Invoke gl_MUSL_LIBC.
* lib/vasnprintf.c (VASNPRINTF): On musl libc, when WIDE_CHAR_VERSION,
- force pad_ourselves to be 1,
- don't use %n.
Fix zero-padding when the result starts with a prefix "0x" or "0b".
* modules/vasnwprintf (Files): Add musl.m4.
* doc/posix-functions/swprintf.texi: Mention two musl libc bugs.
