Updated GH Unix build configurations

- Added support to build 32-bit versions of libModSecurity on Linux
- Added support to build libModSecurity using clang on Linux (both
  64-bit and 32-bit versions)
- Fixed macOS dependencies to include yajl, not only because it is
  a required dependency, but because tests were not being run on
  macOS builds without it.
- Added build 'without libxml' to Linux & macOS configurations.
- Added build 'without ssdeep' to Linux configurations (already in macOS
  configuration)
- Added build 'with lmdb' to Linux & macOS configurations, replacing the
  existing one 'without lmdb' because by default LMDB is disabled if not
  explicitly turn on in configure.
- Removed 'without yajl' build because it's a required 3rd party
  dependency.
- Added bison & flex dependencies to enable parser generation.
