libarchive: disable linking with pcre2

Looks like libarchive v3.7.3 adds support for pcre2 (https://github.com/libarchive/libarchive/commit/d1231a7ea7df4db6ddba73f06df67dbab0174a5c).

Because of this, the following build error is observed (in the case pcre2 is compiled before libarchive):
Package libarchive is missing dependencies for the following libraries:
libpcre2-8.so.0
libpcre2-posix.so.3

So let's disable linking with pcre2, just like linking with pcre was disabled before.
