gpioinfo: Clean up scandir allocations

==3017== 176 (80 direct, 96 indirect) bytes in 1 blocks are definitely lost in loss record 2 of 2
==3017==    at 0x483F6C7: malloc (in /usr/libexec/valgrind/vgpreload_memcheck-amd64-linux.so)
==3017==    by 0x491CE92: ??? (in /lib/libc.so.6)
==3017==    by 0x10AAAC: main (gpioinfo.c:215)

The entires must be freed, and then the array itself.
