perl: update 5.38.2 -> 5.40.0

Update rdepends generator to account for new version specifiers
(v{version} instead of just {version}) and exclude a few more
external modules detected at runtime.

Adjust musl configuration to set custom LC_ALL handling
(musl doesn't follow glibc in that, see the last few comments here:
https://github.com/Perl/perl5/issues/22375 ).

Adjust ptest packaging to add a dummy Makefile for 'make perl
releases' test (otherwise the packaging specifically excludes makefiles).

(From OE-Core rev: 1c1cfae53564c836555ace926295cf88109b8c9f)
