random.c: fix failures on old Linux
This follows the behavior of fill_random_bytes_urandom and fixes the following failures I encountered on my old machine: 1) Error: TestSecureRandom#test_s_random_bytes_without_openssl: NotImplementedError: No random device $RUBYDIR/lib/securerandom.rb:66:in `gen_random' $RUBYDIR/lib/securerandom.rb:94:in `random_bytes' $RUBYDIR/test/test_securerandom.rb:12:in `test_s_random_bytes' $RUBYDIR/test/test_securerandom.rb:97:in `block in test_s_random_bytes_without_openssl' $RUBYDIR/lib/tmpdir.rb:88:in `mktmpdir' $RUBYDIR/test/test_securerandom.rb:85:in `test_s_random_bytes_without_openssl' 2) Error: TestSecureRandom#test_s_urlsafe_base64: NotImplementedError: No random device $RUBYDIR/lib/securerandom.rb:66:in `gen_random' $RUBYDIR/lib/securerandom.rb:94:in `random_bytes' $RUBYDIR/lib/securerandom.rb:164:in `urlsafe_base64' $RUBYDIR/test/test_securerandom.rb:131:in `block in test_s_urlsafe_base64' $RUBYDIR/test/test_securerandom.rb:130:in `times' $RUBYDIR/test/test_securerandom.rb:130:in `test_s_urlsafe_base64' 3) Error: TestSecureRandom#test_uuid: NotImplementedError: No random device $RUBYDIR/lib/securerandom.rb:66:in `gen_random' $RUBYDIR/lib/securerandom.rb:94:in `random_bytes' $RUBYDIR/lib/securerandom.rb:230:in `uuid' $RUBYDIR/test/test_securerandom.rb:160:in `test_uuid' * random.c (fill_random_bytes_syscall): return -1 for error * random.c (fill_random_bytes): try urandom on syscall failure git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51183 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
