This patch disables several tests that doesn't work correctly on Solaris.

test_gdb is not deterministic and sometimes fails for unimportant reasons (only
when ran with gmake test from component root).

test_unicodedata needs to download additional data.
[Not for upstream]

test_time changes skip reason string to reflect the actual platform.
[Can be offered upstream]

test_socket fixes problem with sparc specific behavior of CMSG_SPACE(). Needed
values are not linear as the test expects and that might cause an exception for
last byte. Other problems in this test are related to known issues also
affecting other platforms. [Can be at least reported upstream]

test_re those two test are probably also locale related but I have no idea what
is the root cause of these... [Should be reported upstream]

test_pyexpat exception output is slightly different most likely due to platform
differences. We can safely comment it out. [Not for upstream]

test_tcl should be investigated more [Should be reported upstream]

test_float is another locale related issue. [Should be reported upstream]
https://github.com/python/cpython/commit/aa967ec4d4c2fc844f8f16b339140b050ae4d5e2

test_pkgutil doesn't expect that pkg module exists. [Not for upstream]
