relicense 'reallocarray' to LGPLv2+?

[Daiki Ueno]

Hello Darshit,

I'd like to use the 'reallocarray' module[1] for the integer overflow
hardening in GnuTLS[2].

Currently the module is licensed under "LGPL" (which I believe means
LGPLv3+), while the library part of GnuTLS requires the imported code to
be LGPLv2+.  Therefore I would like to ask your permission to change it
to "LGPLv2+".  Would you agree with that?
