Hello,  please review this small  change that enhances logging a bit .

When reading the fcinfo - file (fontconfig info file) we currently have very limited logging.
This should be enhanced to get more info in case of errors , and to have at least some info in the log when -Dsun.java2d.debugfonts=true is set.

Currently the logging   writes  a ton of info  about lots of non-existant  files , but misses the fcinfo file .

Example output , we run here with  -Dsun.java2d.debugfonts=true   set   :   (with my  added   "successfully parsed the fontconfig file at ..."  from the patch  )
