[C++] Use same regex code at ZTSClient

[equanz]

Motivation

#9533 causes some degraded behaviors at ZTSClient.

1. when using boost::regex
   • can't set path at file scheme
2. when using std::regex
   • can't set relative path like file:./path/to/private.key

I'd like to fix this issue.

Modifications

• Use same regex code between boost and std like this
• Fix regex to be able to capture relative path like file:./
