snort3: enable/disable options based on package availability

snort3: enable/disable options based on package availability

This simplifies checks enabling/disabling features, if packages are present
instead of having checks for specific architectures.

TCMALLOC_LIBRARIES is removed as it's auto-detected, unlike vectorscan
which requires explicit HS_INCLUDE_DIRS.

Fixes: 126364e105fbcfde0617f58c39048c7d56c17a06 ("snort3: refactor architecture-specific dependencies and CMake options")
