packaging: install/package deps if not marked IsHideFromMake

TransitivePackagingSpecs() gathers transitive "install/package"
dependencies.

Previously, IsInstallDepNeeded(depTag) was checked. But, in this way,
some stub libraries which are marked as "HideFromMake()" to avoid
install/package can be gathered.

For example, libdexfile is not installed even if it is one of
libdexfile_support's runtime_libs because it is a stub library and the
impl is provided by "art" apex.

So when gathering transitive deps "IsHideFromMake()" is checked and if
the dep is hidden (so, not supposed to be installed) then the dep
(and its deps) is ignored.

Test: m nothing
Test: m microdroid (libdexfile shouldn't be included in system/lib)
