[PATCH 0/2] scripts/make-erofs.sh: run mkdir/chmod less

[Alyssa Ross <hi@alyssa.is>]

This is an alternative to Demi's proposal[1] to speed this up.
This implementation has the advantage that it does not impose an
ordering requirement on the inputs.  Nevertheless, it runs just as
fast, if not faster (first commit is main; second is Demi's patch;
third is this series):

| Command                   | Mean [s]       | Min [s] | Max [s] | Relative    |
|---------------------------+----------------+---------+---------+-------------|
| =make (commit = 2551f9e)= | 13.275 ± 0.853 |  11.881 |  16.074 | 1.18 ± 0.11 |
| =make (commit = 28fc640)= | 11.467 ± 0.729 |  10.063 |  14.588 | 1.02 ± 0.09 |
| =make (commit = 6c3d020)= | 11.215 ± 0.720 |   9.947 |  15.616 | 1.00        |
