dtc: Use a consistent type for basenamelen

Browse source 
The basenamelen member in the node structure is set in all cases to
a positive value, the length of the basename string. Also it is used as
parameters on function expecting a size_t type.

Further more an implicit cast of strspn() returned value from size_t to
int is needed in checks.c to avoid a signed/unsigned compilation warning
when this value is checked.

This member has no reason to be a signed integer and its obvious type is
size_t.

Be consistent and fix its type.
