package/bats-file: new package

bats-file is a helper library providing common filesystem related
assertions and helpers for Bats.

This library does not provide an installer. Manually install the files
under /usr/lib/bats/bats-file which is what the Arch Linux package
does[1]. This makes the library loadable using `bats_load_library`[2].

+	  bats-file is a helper library providing common filesystem
+	  related assertions and helpers for Bats.
+
+	  Assertions are functions that perform a test and output
+	  relevant information on failure to help debugging. They return
+	  1 on failure and 0 otherwise. Output, formatted for
+	  readability, is sent to the standard error to make assertions
+	  usable outside of @test blocks too.
