Revert fwalk/sfp locking to fix concurrent reads
The locking can fail in a couple of ways: - A concurrent fread from an unbuffered or line-buffered file flushes the output of other line-buffered files, and if _fwalk locks every file, then the fread blocks until other file reads have completed. - __sfp can initialize a file lock while _fwalk is locking/unlocking it. For now, revert to the behavior Bionic had in previous releases. This commit reverts the file locking parts of commit 468efc80da2504f4ae7de8b5e137426d44dda9d7.
