libsensors: Prevent warning with glibc >= 2.20

Since glibc 2.20, the usage of _BSD_SOURCE is deprecated. Fix it like described here:

https://sourceware.org/glibc/wiki/Release/2.20#Deprecation_of__BSD_SOURCE_and__SVID_SOURCE_feature_macros

Inspired from a similar patch by Wolfram Sang for i2c-tools.
