Describe the bug Missing dependency: When trying to (re)build rspamd in a clean environment, the required hyperscan library cannot be found. Adding libhyperscan-dev to Build-Depends: in debian/control fixes this.

Steps to Reproduce

# apt-get source rspamd
[...]
# dpkg-buildpackage -us -uc -ui -F
[...]
-- Checking for one of the modules 'libhs'
CMake Error at cmake/ProcessPackage.cmake:71 (MESSAGE):
  Cannot find library hs for package HYPERSCAN
Call Stack (most recent call first):
  cmake/Hyperscan.cmake:4 (ProcessPackage)
  CMakeLists.txt:252 (include)


-- Configuring incomplete, errors occurred!
make[1]: *** [debian/rules:31: configure_release] Error 1
make[1]: Leaving directory '/build/packages/deb-rebuild.wpZH9VKl/rspamd-3.7.3'
make: *** [debian/rules:26: build] Error 2
dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2

Expected behavior All required dependencies are listed in debian/control and the (re)build succeeds.

Versions

OS: Ubuntu 20.04 LTS/22.04 LTS Tested rspamd versions: 3.7.1, 3.7.3

The reason for it is because we intend to use vectorscan on ARM as a static library. It might be easily remedied some time in the future when vectorscan would be packaged by all supported Debian-alikes given those versions would be usable.
