aarch64/fpu_control.h: Don't use gcc-internal types

Commit 618001c26e224fd4aff72b8e5530498acbad747a introduced fenv support
from glibc. However that uses type names which are gcc-internal and not
supported by compilers such as clang. Clang also does not have builtins
for accessing the fpsr / fpcr registers, so it needs to use the
fall-back path.

Include stdint.h and use uint64_t instead of __uint64_t to make the code
work with clang as well.
