libdbi-perl: add missing perl module ptest RDEPENDS

All 6 ptest failures (t/31methcache, t/35thrclone, t/40profile,
t/41prof_dump, t/42prof_data, t/43prof_env) are missing runtime perl
modules, in two groups:

Module::Load, required by DBI/Profile.pm line 682:

  Can't locate Module/Load.pm in @INC ... at
  /usr/lib/perl5/vendor_perl/5.44.0/aarch64-linux/DBI/Profile.pm line 682.

This breaks t/40profile and t/43prof_env directly, and cascades into
t/41prof_dump and t/42prof_data: once DBI/Profile.pm fails to compile,
%INC is poisoned, so those two report "Attempt to reload DBI/Profile.pm
aborted" and a missing DBI::Profile->flush_to_disk method rather than
the underlying cause. Provided by perl-module-load.

Test2::Util::Sig, required by Test2/IPC/Driver/Files.pm line 18, which
Test::Builder pulls in when a test enables Test2 IPC (threads/forking):

  Can't locate Test2/Util/Sig.pm in @INC ... at
  /usr/lib/perl5/5.44.0/Test2/IPC/Driver/Files.pm line 18.

This makes Test::More unusable in t/31methcache and t/35thrclone, which
is why only those two of the many Test::More-based tests fail. Provided
by perl-module-test2-util-sig.
