[cairo] [PATCH v2 2/2] test: Fix issues reported by cppcheck static analysis tool

[Ravi Nanjundappa]

cppcheck analysis tool reports the following issues when run on the
latest Cairo source.

$ grep "(error)"  cppcheck_error_log.txt
[test/pdf-mime-data.c:58]: (error) Possible null pointer dereference: file - otherwise it is redundant to check if file is null at line 53
[test/pdf-mime-data.c:75]: (error) Resource leak: fp
$

The proposed changes fixes the above issues.
