[bug-libunistring] Test suite patches to clear Asan findings

[Jeffrey Walton]

Hi Everyone/Bruno,

The attached patch clears Asan findings in libunicode 0.9.10. The
patch allows the library to pass acceptance testing with no findings
or errors.

I am not sure about tests/test-float.c. It was added for old Apple
platforms. It looks like libunistring handles LDBL_MANT_DIG=106
already, so the patch gets through the self tests without failure.
