When I run some tests in gdb.server (fox example
gdb.server/ext-attach.exp) on Ubuntu 20.04 with separate debug info for
glibc installed, they often time out. This is because GDB reads the
debug info through the remote protocol which is particularly slow:
attach 316937

FAIL: gdb.server/ext-attach.exp: attach to remote program 1 (timeout)
This is avoided in gdbserver boards by adding "set sysroot" to GDBFLAGS
(see boards/local-board.exp), which makes GDB read files from the local
filesystem. But gdb.server tests spawn GDBserver directly, so are ran
even when using the default unix board, where the "set sysroot" isn't
used.
Modify these tests to append "set sysroot" to the GDBFLAGS, a bit like
lib/local-board.exp does.
One special case is gdb.server/sysroot.exp, whose intent is to test
different "set sysroot" values. For this one, increase the timeout when
testing the "target:" sysroot.
gdb/testsuite/ChangeLog:
* gdb.server/abspath.exp: Append "set sysroot" to GDBFLAGS.
* gdb.server/connect-without-multi-process.exp: Likewise.
* gdb.server/exit-multiple-threads.exp: Likewise.
* gdb.server/ext-attach.exp: Likewise.
* gdb.server/ext-restart.exp: Likewise.
* gdb.server/ext-run.exp: Likewise.
* gdb.server/ext-wrapper.exp: Likewise.
* gdb.server/multi-ui-errors.exp: Likewise.
* gdb.server/no-thread-db.exp: Likewise.
* gdb.server/reconnect-ctrl-c.exp: Likewise.
* gdb.server/run-without-local-binary.exp: Likewise.
* gdb.server/server-kill.exp: Likewise.
* gdb.server/server-run.exp: Likewise.
* gdb.server/solib-list.exp: Likewise.
* gdb.server/stop-reply-no-thread.exp: Likewise.
* gdb.server/wrapper.exp: Likewise.
* gdb.server/sysroot.exp: Increase timeout when testing the
target: sysroot.
