Update file to 5.37

Changelog:

• Make sure that continuation separators are printed with -k within softmagic
• Change SIGPIPE saving and restoring during compression to use sigaction(2) instead of signal(3) and cache it.
• Cache stat(2) calls more to reduce number of calls
• Handle --mime-type and -k correctly.
• Switch decompression code to use vfork() because tools like rpmdiff and rpmbuild call libmagic with large process footprints
• --enable-zlib, did not work.
• Improve regex efficiency
