[Buildroot] [git commit branch/2020.11.x] package/libeXosip2: fix build with libressl

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=00b1d477e5590dfba42b7111921a3fef1f49b6b6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.11.x

Build with libressl is broken since version 5.1.0 and
https://git.savannah.nongnu.org/cgit/exosip.git/commit/?id=d7488b7bbf59870192372384ef338a44be23e888

For an unknown reason, we only have one autobuilder failure with version
5.2.0

Fixes:
