[UNIKRAFT PATCH RFCv4 34/35] lib/posix-user: Export several posix-user interfaces

[Jia He <justin.he@xxxxxxx>]

Without these posix-user interfaces, building nginx on arm64 will
trigger linking failures as follows:

.../ngx_process_cycle.c:828: undefined reference to `geteuid'
.../ngx_process_cycle.c:829: undefined reference to `setgid'
.../ngx_process_cycle.c:836: undefined reference to `initgroups'
.../ngx_process_cycle.c:853: undefined reference to `setuid'
<snip>
