[PATCH v2] ui-snapshot.c: Terminate cgit_snapshot_formats[] properly

[Lukas Fleischer]

According to section 6.7.8 of the C89/C99 standards, initializer lists
must not be empty. Explicitly set the first field to zero which is the
standard way of initializing a structure to all zeros.

This also fixes a GCC warning seen with "-Wmissing-field-initializers".
