[PATCH -perfbook 1/3] adjustindexformat.pl: Cope with recent hyperref change

[Akira Yokosawa <akiyks@gmail.com>]

hyperref 7.01n (released in July 2025) made a change in the name of
its macro for formatting page counts in index [1].  It ended up in
a regression in our Index pages, namely, missing most page counts
with bold shape or underlined.
This issue is observed in recent CI-builds at
https://gitlab.com/linux-kernel/perfbook/.

Add regex'es to cover the patterns of "hyperxindexformat{...}".
   (in addition to those for existing "hyperindexformat{...}")
