add "getline" and "getdelim" to notmuch.sym on systems lacking it

[Matthias Guedemann]

hi all,

OpenBSD does not provide the getline function. This is correctly
detected in the configure script, but the version script only emits the
Xapian*Error and notmuch_... symbols leading to undefined symbol errors
for getline and getdelim.

Therefore I added two lines to gen-version-script.sh to also emit
getline and getdelim if needed, tested on OpenBSD 5.0-current and Debian
on current git head.

regards
Matthias
