Public bug reported:
Take kernel module intel-ish-ipc for example, it has two firmware
declarations:
```
$ modinfo intel-ish-ipc | grep ^firmware
firmware: intel/ish/ish_*.bin
firmware: intel/ish/ish_lnlm.bin
```
And with additional custom ISH firmware installed from bug 2094768,
update-initramefs gives:
```
$ update-initramefs -v -u -k $(uname -r)
...
dracut-install: Missing firmware intel/ish/ish_*.bin for kernel module
intel_ish_ipc
dracut-install: mkdir '/var/tmp/mkinitramfs_9uk7FI/lib/firmware/intel/ish'
dracut-install: cp
'/lib/firmware/intel/ish/ish_lnlm_39ceeaf8_58.7724.2.bin.zst'
'/var/tmp/mkinitramfs_9uk7FI/lib/firmware/intel/ish/ish_lnlm_39ceeaf8_58.7724.2.bin.zst'
dracut-install: ln -s 'ish_lnlm_39ceeaf8_58.7724.2.bin.zst'
'/var/tmp/mkinitramfs_9uk7FI/lib/firmware/intel/ish/ish_lnlm.bin.zst'
...
```
In source code for /usr/lib/dracut/dracut-install, that is, source
package dracut, file src/install/dracut-install.c, function
install_firmware, it tries to invoke `glob()` with full path expanded
from "intel/ish/ish_*.bin", but while all the binaries were compressed,
this matches no file and none of the custom ISH firmware blobs will be
installed.
