Bump to v0.111

Changes were made to bootstrap reinstallation logic in 107927f5, but it wasn't considering that PREFIX may be a symlink file to a directory instead of a directory file. With this commit, the previous behaviour of termux is restored where PREFIX can optionally be a symlink to a valid directory where the symlink isn't broken/dangling.
