[Filesystem] Fix crash in filesystem_provider_deviced.cc on emulator

When generating id from UUID out_of_range was thrown by std::stoul,
because long is too short (4 bytes on 32 bit simulator).
Changed id to be hash of UUID. Previously only first two fields
(6 bytes) were used.

[Verification]
tct-filesystem-tizen-tests automated and manual test pass 100%
tct-systeminfo-tizen-tests automated test pass 100%
