Change pcre2_malloc() in a way that'll make it easier for a debugging fprintf() to spew out the allocated pointer.

This doesn't introduce any functional change, it just makes a subsequent commit's diff easier to read. Changes code added in 513f2b0bbd4 (grep: make PCRE2 aware of custom allocator, 2019-10-16).
