package/ecryptfs-utils: remove libnss gcc bug dependency

Package libnss had a BR2_TOOLCHAIN_HAS_GCC_BUG_85862 dependency and
since ecryptfs-utils depends on libnss it does have this dependnecy as
well.

However, gcc bug 85862 has been worked around now in libnss by
disabling optimization, so libnss no longer has this
BR2_TOOLCHAIN_HAS_GCC_BUG_85862 dependency. We can therefore drop it
from ecryptfs-utils as well.
