fix(libselinux): add patch to link with pcre2 from conan instead of o…

[ledocc]

…ne from system

Specify library name and version: libselinux/3.3

Problem:
On my centos 7.9 docker image, I have not libpcre2-8.so installed.
When package libselinux build, utils executables failed to link with libselinux because libpcre2-8 is not found.

Explication:
In the libselinux Makefile, libselinux.so library link with libpcre2-8.so.
Then executables in utils sub-directory are compiled and linked with libselinux.so. But on link command line, no information were provide to find libselinux dependencies (ex: -L/path/to/pcre2/lib_directory), so linker look for libpcre2 on the system, and this work fine in many case ... excepted when libpcre2-8.so in not installed on the system

Solution:
Provided information to linker to find libselinux dependencies.

Info:
Executables in utils sub-directory are not installed in libselinux package, so we could :

• patch the Makefile to disable the build utils sub-directory
• remove utils sub-directory before run the build
• any other solution to not build utils sub-directory
• do nothing
• add them to package

thought ?

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

Hi @ledocc
This sounds like it could potentially also fix this issue here: #15798

I can check this tomorrow :)
