nsenter: fix parsing of -t, -S and -G options
-t, -S and -G each take mandatory integer arguments. getopt32long()'s
option string syntax for this type of argument is 'c:+', however nsenter's
opt_str uses 'c+', which specifies two options 'c' and '+' which do not
take arguments. This means that giving a target PID causes nsenter to
exit and print the usage string:
# nsenter -t1 sh
nsenter: unrecognized option: 1
BusyBox v1.27.2 (2017-12-12 10:41:50 GMT) multi-call binary.
...
The long form options are also broken:
# nsenter --setuid=1000 --setgid=1000 sh
BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
...
`nsenter --target=<pid> sh` parses correctly and appears to work, but
<pid> is ignored and set to 0. This doesn't raise an error unless one
of the namespace arguments is also given:
# ./busybox_unstripped nsenter --target=42 sh
# exit
# ./busybox_unstripped nsenter -n --target=42 sh

nsenter: Rename --network option to --net
In nsenter from util-linux, the long version of the -n option is

Confusingly, until commit

claimed that the long option was indeed called --net; after that commit
long options are not listed at all.

Upstream commit:

expand: Fix buffer overflow in expandmeta
The native version of expandmeta allocates a buffer that may be
overrun for two reasons. First of all the size is 1 byte too small
but this is normally hidden because the minimum size is rounded
up to 2048 bytes. Secondly, if the directory level is deep enough,
any buffer can be overrun.
This patch fixes both problems by calling realloc when necessary.
