gnu: ldc: Fix building on riscv64-linux.

* gnu/packages/dlang.scm (ldc)[arguments]: Add a configure-flag to link
the executables with -latomic.  Adjust the 'disable-problematic-tests
phase to disable 2 tests which fail on riscv64-linux and delete some
tests which fail on riscv64-linux.  Adjust the custom 'check phase to
skip several tests when building on riscv64-linux.
