[PATCH 04/10] grep/pcre2: prepare to add debugging to pcre2_malloc()

[Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>]

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).
