<https://github.com/The-OpenROAD-Project/OpenLane/issues/729|#729 read_lib fails when trimmed.lib contains two libraries>
New issue created by <https://github.com/hpretl|hpretl>
*Description*

After solving <https://github.com/The-OpenROAD-Project/OpenLane/issues/727|#727>, the flow script fails further down at step 7. Here, the `read_lib $::env(LIB_SYNTH)` in `replace.tcl` fails, because the file `/openlane/designs/audiodac/runs/RUN_2021.11.23_16.42.33/tmp/trimmed.lib` contains two `library` entries:

```
line 1:
library ("sky130_fd_sc_hvl__tt_025C_3v30") {

```

and

```
line 31779:
library ("sky130_fd_sc_hvl__tt_025C_3v30_lv1v80") {

```

*Environment*

See <https://github.com/The-OpenROAD-Project/OpenLane/issues/727|#727>

*Reproduction Material*

See <https://github.com/The-OpenROAD-Project/OpenLane/issues/727|#727>

*Expected behavior*

Not crashing with error.
