build-unit-test-docker: Ensure pthread flag is -pthread

googletest and googlemock incorrectly use CMAKE_THREAD_LIBS_INIT in the
Cflags declaration for their .pc files. We can make this work by
ensuring that CMAKE_THREAD_LIBS_INIT is always -pthread which works as a
Cflag and Linker flag.

See google/googletest#2006
