Adhemerval Zanella eeb7b079d5 stdlib: Fix __libc_message_impl iovec size (BZ 32947) 
The iovec size should account for all substrings between each conversion
specification.  For the format:

  "abc %s efg"

The list of substrings are:

  ["abc ", arg, " efg]

which is 2 times the number of maximum arguments *plus* one.

This issue triggered 'out of bounds' errors by stdlib/tst-bz20544 when
glibc is built with experimental UBSAN support [1].

Besides adjusting the iovec size, a new runtime and check is added to
avoid wrong __libc_message_impl usage.

Checked on x86_64-linux-gnu.
