c32is*, c32to*, c32width, wcswidth: Relax license

[Bruno Haible]

Some modules for char32_t convenience functions are currently under
'LGPLv3+ or GPLv2+' license. But I want to make the 'mbchar' module
depend on them, and the 'mbchar' module is under LGPLv2+. Therefore
these modules need to be under LGPLv2+ as well.

I can relax the license of these module, because I am the sole
contributor of copyright-relevant changes to the corresponding
files in lib/.

Done as follows:
