Fix quoting of #pragma comment for PS4.

Fix quoting of #pragma comment for PS4.

This is the PS4 counterpart to r229376, which quotes the library name if the
name contains space. It was discovered that if a library name contains both
double-quote and space characters, quoting the name might produce unexpected
results, but we are mostly concerned with a Windows host environment, which
does not allow double-quote or slashes in file/folder names.
