MDL-74823 lib: normalize line endings for HTMLPurifier
Prior to this change, all the line endings in the imported HTMLPurifier
library were using CRLF (\r\n aka Windows style), but the HTMLPurifier
source and also the downloadable artefacts use LF (\n aka Linux style)
as line endings. This has been the case since
510d190382003985eafd6f4407190d43509016a5 when with the commit
"MDL-38672 import HTML Purifier 4.5.0" all line endings were changed
from LF to CRLF. There was no comment in the commit on why this change
was done.

As the original source uses LF, this commit partly reverts
510d190382003985eafd6f4407190d43509016a5 and goes back to LF as line
endings.
