linux-user: add strace for getuid(), gettid(), getppid(), geteuid()

Browse Source 
Improve strace support for syscalls getuid(), gettid(), getppid()
and geteuid(). Since these system calls don't have arguments, "%s()"
is added in the corresponding strace.list entry so that no arguments
are printed.

getuid:
Prior to this commit, typical strace output used to look like this:
4894 getuid(4894,0,0,274886293296,-3689348814741910323,4832615904) = 1000
After this commit, it looks like this:
4894 getuid() = 1000

gettid:
Prior to this commit, typical strace output used to look like this:
8307 gettid(0,0,64,0,4832630528,4832615840) = 8307
After this commit, it looks like this:
8307 gettid() = 8307

getppid:
Prior to this commit, typical strace output used to look like this:
20588 getppid(20588,64,0,4832630528,4832615888,0) = 20625
After this commit, it looks like this:
20588 getppid() = 20625

geteuid:
Prior to this commit, typical strace output used to look like this:
20588 geteuid(64,0,0,4832615888,0,-9151031864016699136) = 1000
After this commit, it looks like this:
20588 geteuid() = 1000
