examples/inspect: use malloc/free

Instead of aom variants. This fixes a link error when using
`-DBUILD_SHARED_LIBS=1` after:
d737ca3ebe exports_com: rm aom_{malloc,free}

`aom_malloc` and `aom_free` are internal functions. The standard library
functions are sufficient for this example.

Thanks to Dan Fandrich (dan at telarity) for pointing out the issue.
