taskset: fix description of `-c` option in the man page
Commit 42f15e9848dc07e86a2b80c742a0179aaced6c71 introduced a certain
inaccuracy in -c option description; it is not _the option with an argument_,
but it is the flag that changes interpretation of `mask` parameter.
The difference is almost not noticeable, but there are one corner case where it is:
taskset -c 1 -p $$
fails (but it would work if 42f15e was correct). Instead,
taskset -c -p 1 $$
works (but it should not have if 42f15e was correct).

Depending on architecture and kernel version, personality
syscall is either capable or incapable of returning an error.
If the return value is not an error, then it's the previous
personality value, which can be an arbitrary value
undistinguishable from an error value.
To make things clear, a second call is needed.

build-sys: disable login-utils if shadow.h or utmp.h is missing
Actually we could have also used UL_REQUIRES_LINUX because our
utmp usage and the shadow.h header is unlikely to be portable.
However only requiring these headers may help others who are
curious what needs to be done to port something.
Note, we could easily make the utmp stuff more portable by using
utmpx which is POSIX standard and on LINUX (glibc) basically just
renaming work. See getutxent(3).
