gstvalue: fix compilation warning in "holds" macros

Browse source 
GST_VALUE_HOLDS_... macros may cause -Waddress warning
on gcc if GValue is allocated on stack:

gstvalue.h:145:46: warning: the comparison will always
evaluate as ‘true’ for the address of ‘v’ will never
be NULL [-Waddress]

 #define GST_VALUE_HOLDS_CAPS(x)         ((x) != NULL &&
  G_VALUE_TYPE(x) == _gst_caps_type)

Fixes #653
