RFR: 8336529: (fs) UnixFileAttributeViews setTimes() failing on armhf, Ubuntu noble [v3]

[Vladimir Petko]

> time_t transition in Debian/Ubuntu left 32 bit time_t  symbols in glibc. 
> 
> Looking up 'futimens' via dlsym returns 32 bit version of the function.  
> This is causing failure to set last modified time (e.g. instead of year 2017 we get 1976 in the test).
> Using the function directly correctly calls 64 bit versions. 
> 
> When we lookup functions with time_t arguments through dlsym() calls we should use 64 bit versions.
> 
> This MR adds a function to lookup 64 bit functions when time_t size is greater than 32 bit in line with the existing [time_t patch](https://evolvis.org/plugins/scmgit/cgi-bin/gitweb.cgi?p=alioth/openjdk-8.git;a=blob;f=debian/patches/t64-dlsyms.diff;h=b2cc8f8a00244bc44900366ed08d7f246ad09904;hb=4c5085cd49fcdc04405e9039705935fde08644a7)
