uml: userspace files should call libc directly
A number of files that were changed in the recent removal of tt mode
are userspace files which call the os_* wrappers instead of calling
libc directly. A few other files were affected by this, through
This patch makes these call glibc directly.
There are also style fixes in the affected areas.
os_print_error has no remaining callers, so it is deleted.
There is a interface change to os_set_exec_close, eliminating a
parameter which was always the same. The callers are fixed as well.
os_process_pc got its error path cleaned up.
