mesa: fix empty program log length
In case we have empty log (""), we should return 0. This fixes
Khronos WebGL conformance test 'program-infolog'.
From OpenGL ES 3.1 (and OpenGL 4.5 Core) spec:
"If pname is INFO_LOG_LENGTH , the length of the info log, including
a null terminator, is returned. If there is no info log, zero is
returned."
v2: apply same fix for get_shaderiv and _mesa_GetProgramPipelineiv (Ian)
