tdf#147250 configure: default to --with-system-nss on Linux
NSS is very ABI compatible and part of current LSB 5.0 and so it should
just work to use the one from the system, i'm not aware of a Linux that
doesn't ship it.
There used to be some feature patch in external/nss but this was removed
years ago, now it just contains build fixes.
Problems can occur if a mixture of system and bundled NSS libraries is
loaded, if first an old version .so is loaded and then newer version .so
depends on it but can't find some required symbol.
See for example:
https://www.mail-archive.com/libreoffice@lists.freedesktop.org/msg287043.html
Another issue is that e.g. Fedora ships libnsspem.so in the nss-pem
package, which may cause trouble in ASAN builds, where the internal NSS
is built to call __asan_poison_memory_region but the system
libnss-pem.so doesn't call __asan_unpoison_memory_region so we get:

Also, with system NSS, things like p11-kit integration become
responsibility of the OS.
