d: Remove gdc.test/runnable/dbitfieldsdm.d [PR124158]

The gdc.test/runnable/dbitfieldsdm.d test FAILs on SPARC:

FAIL: gdc.test/runnable/dbitfieldsdm.d   execution test

As described in the PR, it dies with SIGBUS due to an unaligned access,
which doesn't work on a strict-alignment CPU.

However, the test has a comment

	Note that this test is for win32 only

and should already be disabled on various systems:

	DISABLED: win32mscoff win64 linux freebsd osx

The DISABLED annotation isn't handled by the gdc DejaGnu framework and
there's no support for the usual dg-* annotations, so this patch removes
the test.

Tested on sparc-sun-solaris2.11 and i386-pc-solaris2.11.
