Bug #77374 main.mysqld_safe test fails if only mysqld-debug was built

Description:
main.mysqld_safe test fails if the server binary is named mysqld-debug and there is no binary named mysqld.

How to repeat:
Do an out-of-source build on a clean directory with CMake options that build mysqld-debug:

cmake ../mysql-server/ -DBUILD_CONFIG=mysql_release -DWITH_DEBUG=ON -DWITH_BOOST=...
...
make
...
$ ./mtr --debug-server mysqld_safe
...
main.mysqld_safe                         [ fail ]

CURRENT_TEST: main.mysqld_safe
mysqltest: In included file ./include/wait_until_connected_again.inc at line 29:
included from /Users/laurynas/percona/mysql-server/mysql-test/t/mysqld_safe.test at line 48:
At line 29: Server failed to restart

The result from queries just before the failure was:
use test;

Suggested fix:
mysqld_safe invocation in the test needs a correct --mysqld option passed.

Thank you for the bug report. Changed OS to Linux (on Windows that test isn't supported i.e).

This is a duplicate of my own previous bug 71117, which I completely forgot about. This one has a patch though
