darwin: cut DYLD_LIBRARY_PATH from default modules
This commit removes the DYLD_LIBRARY_PATH variable from the default modules.yaml for darwin. The rationale behind deleting this environment variable is that paths in this environment variable take precedence over the default locations of libraries (usually the install path of the library), which can lead to linking errors in some circumstances. For example, executables intended to link with Apple's system BLAS and LAPACK will instead link to a spack-installed implementation (e.g., OpenBLAS), causing runtime errors. These errors are resolved by instead relying on paths set in DYLD_FALLBACK_LIBRARY_PATH, which is lower in precedence than default locations of libraries.
