util: Make the initial allocation bigger for xreadlinkat()
Most symlinks are more than 1 character long, so rather than wasting time with 1, 2, 4, ... when we don't have a good guess for the length, start with a bigger one. Credit to https://twitter.com/RichFelker/status/1306321019108556806 for reminding me of this.
