xenoprof: Use uint64_t explicitly for internal calls

A recent changeset to make XENOPROF_ESCAPE_CODE consistent across
32- and 64-bit builds caused a build failure, because values were
passed through functions as "unsigned long".  Replace these with
uint64_t explicitly.

Also remove redundant function prototype from perfmon.c, now that
it's in a header file.
