linux-user/hexagon: Use generic target_stat64 structure

Linux Hexagon port doesn't define a specific 'struct stat'
but uses the generic one (see Linux commit 6103ec56c65c [*]
"asm-generic: add generic ABI headers" which predates the
introduction of the Hexagon port).

Remove the target specific target_stat (which in fact is the
target_stat64 structure but uses incorrect target_long and
ABI unsafe long long types) and use the generic target_stat64
instead.
