test_fsize_not_too_big() fails on Solaris #154326
Description
Bug report
test_resource.test_fsize_not_too_big() accepts that a platform can silently convert too large limits to RLIM_INFINITY, but only models the glibc quirk on 32-bit platforms.
Solaris converts every limit that does not fit in a signed 64-bit integer, so the test fails there:
AssertionError: (18446744073709551613, 18446744073709551613) not found in [(9223372036854775808, 18446744073709551613)]
RLIM_INFINITY is (rlim_t)-3 on Solaris. Measured on OpenIndiana: limits up to 0x7ffffffffffffffe are stored literally, from 0x7fffffffffffffff they are converted to RLIM_INFINITY.
Only 3.15 and main are affected: in 3.14 and 3.13 expected() accepts RLIM_INFINITY whenever it is negative, which covers Solaris.
