script/autobuild.py: let nm_grep_symbols ignore __gcov_ symbols

Currently the gcov build currently fails with the following error:

samba-libs: [allshared-no-public-nss_winbind] Running nm ./bin/plugins/libnss_winbind.so.2 | egrep -v ' (__bss_start|_edata|_init|_fini|_end)' | egrep -v ' T _nss_winbind_' |egrep ' [BDGTRVWS] ' && exit 1; exit 0; in '/tmp/samba-testbase/samba-libs/.'
