perfcounter: Handle some IO return values

Building perfcounter tools raises the following warnings:

 builtin-record.c: In function ‘atexit_header’:
 builtin-record.c:464: erreur: ignoring return value of ‘pwrite’, declared with attribute warn_unused_result
 builtin-record.c: In function ‘__cmd_record’:
 builtin-record.c:503: erreur: ignoring return value of ‘read’, declared with attribute warn_unused_result

 builtin-report.c: In function ‘__cmd_report’:
 builtin-report.c:1403: erreur: ignoring return value of ‘read’, declared with attribute warn_unused_result

This patch handles these IO return values.
