Subject: [PATCH] xbps-src: Don't unset IFS

If IFS is unset, the shell behaves as if it has the default value of
`<space><tab><newline>`. However, after unsetting IFS, constructs like
```
OFS="$IFS"; IFS=','
...
IFS="$OIFS"
```
(for example in common/xbps-src/shutils/common.sh lines 246-253) have
the effect of setting IFS with an empty value, which breaks
word-splitting. This results in an error like
```
./common/xbps-src/shutils/bulk.sh: line 125: sudo /bin/sh -c: No such file or directory
```
when running `./xbps-src update-sys` with `XBPS_SUCMD` set to the
default value (`sudo /bin/sh -c`).
