pkg/compiler: add glob type

* all: add new typename dirname

The current way to check files under sysfs or proc is:
- define a string to represent each file
- open the file
- pass the fd to write / read / close

The issues above are:
- Need to know what file present on target device
- Need to write openat for each file

With dirname added, which will open one file
in the directory randomly and then pass the fd to
write/read/close.

* all: use typename glob to match filename

Fixes #481
