Fix inname test case

* src/safe.h (unsafe): New flag to allow turning off safe file
operations.
* src/safe.c (safe_xstat, safe_open, safe_rename, safe_mkdir,
safe_rmdir, safe_unlink, safe_symlink, safe_chmod, safe_lchown,
safe_lutimens, safe_readlink, safe_access): When safe file operations
are turned off, skip safe path traversal.  Any symlink checks of the
last path component are still done though.
* src/patch.c (main): When the file to patch is specified on the command
line, turn off safe file operations.
* tests/inname: Fix typo in test.
