RPATH support

• first steps with ld wrapper implemented in https://github.com/hpcugent/easybuild-framework/pull/1613
• TODO:
  • add sanity check (using https://github.com/eliben/pyelftools)
  • allow different rpath methods: env, ld wrapper, compilers wrappers (and support enabling multiple ones at the same time)
  • ensure there's no $LD_LIBRARY_PATH statements in modules (and check for it when loading dep modules)

Q&A

• fix support for --minimal-toolchains
  • currently doesn't work with HierarchicalMNS & co, considering minimal toolchains happens too late
  • cfr. https://github.com/hpcugent/easybuild-framework/issues/1606
  • PR to fix: https://github.com/hpcugent/easybuild-framework/pull/1614
  • dedicated end-to-end test for --minimal-toolchains (w/ HierarchicalMNS would be nice to have)
  • also includes others related fixes
    • fix for GCCcore not being considered because it's only a dep (not a toolchain): https://github.com/hpcugent/easybuild-framework/pull/1576
    • considering existing modules in reverse order: https://github.com/hpcugent/easybuild-framework/pull/1579
