libstdc++: Remove Solaris workaround in 20_util/to_chars/float128_c++23.cc [PR107815]

As described in PR libstdc++/107815, one subtest of
20_util/to_chars/float128_c++23.cc was disabled on Solaris due to a bug
in printf(3C).  This has been fixed since October 2023, so the
workaround can be removed.

Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11, and
x86_64-pc-linux-gnu.
