Subject: configure: fix pkg-config detecting wolfssl
X-Git-Tag: curl-7_73_0~221

configure: fix pkg-config detecting wolfssl

When amending the include path with "/wolfssl", this now properly strips
off all whitespace from the path variable! Previously this would lead to
pkg-config builds creating bad command lines.

Closes #5848
