testsuite: gdc: Require ucn in gdc.test/runnable/mangle.d etc. [PR104739]

gdc.test/runnable/mangle.d and two other tests come out UNRESOLVED on
Solaris with the native assembler:

UNRESOLVED: gdc.test/runnable/mangle.d   compilation failed to produce executable
UNRESOLVED: gdc.test/runnable/mangle.d -shared-libphobos compilation failed
to produce executable
UNRESOLVED: gdc.test/runnable/testmodule.d compilation failed to produce
executable
UNRESOLVED: gdc.test/runnable/testmodule.d -shared-libphobos compilation
failed to produce executable
UNRESOLVED: gdc.test/runnable/ufcs.d   compilation failed to produce executable
UNRESOLVED: gdc.test/runnable/ufcs.d -shared-libphobos compilation failed
to produce executable

[...]

since /bin/as lacks UCN support.

Iain recently added UNICODE_NAMES: annotations to the affected tests and
those recently were imported into trunk.

This patch handles the DejaGnu side of things, adding

	{ dg-require-effective-target ucn }

to those tests on the fly.

Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11 (as and gas each),
and x86_64-pc-linux-gnu.
