Conditionally add uuid_time64 to sym. version map

The symbol uuid_time64 is conditionally defined. It only exists on
32-bit platforms that use the glibc library and enable support for
the 64-bit time_t type.

For all other platforms, the symbol is undefined. As a result, when
ld.lld version 17 or newer is used with default flags, ld.lld will
reject the symbol map with the error:

    version script assignment of 'UUID_2.40' to symbol 'uuid_time64'
    failed: symbol not defined

To fix this issue, the reference to uuid_time64 is changed to
uuid_time64*. The change to a glob pattern satisifies ld.lld and allows
the library to link.
