Ian Lance Taylor 0ce6af9f18 [release-branch.go1.9] misc/cgo/testcshared: use file descriptor 30 for TestUnexportedSymbols
Backport of CL 108537 to 1.9 release branch.

We were using file descriptor 100, which requires the Linux kernel to
grow the fdtable size. That step may sometimes require a long time,
causing the test to fail. Switch to file descriptor 30, which should
not require growing the fdtable.

Updates #23784
Fixes #25278
