libbsd: Fix check if getentropy needs building

[gjasny]

Specify library name and version: libbsd/0.10.0

This patch fixes the check to avoid building getentropy.c in case the system libc already provides that symbol.

Thanks - Seems like a nice backport for me

I'll try to get the new version PR reviewed today too :)

It looks a good back-port as CCI has multiple glibc versions
