pcf: Truncate FT_ULong `nprops' to fit to int PCF_Face->nprops.
* src/pcf/pcfread.c (pcf_get_properties): Load `nprops'
as FT_ULong value from PCF file, but truncate it as
int to fit PCF_Face->nprops. The number of truncated
properties is shown in the trace message.

gxvalid: Extend a few local variables to reduce the casts.
