fix: add randUint64 wrapper for Go 1.21 compatibility

Browse Source 
Implement randUint64() directly in the maphash overlay to ensure compatibility
across Go versions. Go 1.21's randUint64() calls runtime.fastrand64, while
Go 1.22+ calls runtime.rand. The wrapper function bridges to llgo's fastrand64
implementation, avoiding undefined symbol errors on Go 1.21.
