[ruby-core:51627] [ruby-trunk - Bug #7721] test_too_long_path2(TestProcess) fails on mingw32

Issue #7721 has been updated by nobu (Nobuyoshi Nakada).

File 0001-error.c-defer-error-message.patch added
ruby -v set to 38934

NoMemoryError could occur at many places, almostly everywhere creating
a new object, adding a new instance variable, growing up a container
object, etc.  It's just rare in normal cases.

r30682 reduced the sizes from 100MB to 10MB because NoMemoryError is
not intended, but test_too_long_path2 is still consuming double of
test_too_long_path.

I fix these tests instead for the time being.

Another strategy is, similar to NameError::message, keeping the given
parameters untouched and defer generating the message until to_s is
called.  But it's complex considering Marshal.
