package/luvi: bump to version 2.15.0

Luvi 2.14.0 fails to build with GCC 14.x for several reasons due to
too old lua-openssl 0.8.2-0 submodule:

Instead of fixing one by one each issues, update to the latest release
that include lua-openssl 0.9.0-0. Luvi v2.15.0 still have some GCC 14.x
issues, backport two additional patches.

Download luvi sources using git method since the release archive
no longer include the release version in its name [4].

Luvi switched to PCRE2 [5], update the optional dependency.

Update TestLuvi to select PCR2 package.

+Subject: [PATCH] Selectively disable GCC diagnostics in ocsp.c
+
+GCC 14 fails to compile the library because -Wincompatible-pointer-types is now fatal.
+Since the warning is already disabled for clang here, might as well include GCC also.
+Needless to say, this is a workaround and a proper fix would require upstream changes.

+  - rebase on lua-openssl 0.9.0-0

+"lua-openssl triggering the incompatible pointer types error by
