build: Replace deprecated meson functions

Replace deprecated functions with their direct replacements:

 - dep.get_pkgconfig_variable() → dep.get_variable()
 - prg.path() → prg.full_path()
 - source/build_root() → project_source/build_root()

In one case we need meson.global_source_root() that was only
added in meson 0.58, so bump the requirement to that.
