[LTP] [PATCH v3] syscall01: use 32bit syscalls if available

[Cyril Hrubis]

Hi!

Sounds reasonable, since we are attempting to test syscall() and not the
getuid implementation. Also this probably fixes the case where the test
would be executed with UID that does not fit into 16 bits as well.

Pushed, thanks.
