bluez: Fix invalid-pp-token warning found with clang

Browse Source 
We add FIRMWARE_DIR via CFLAGS using escapes for string and clang
option parser flags it

<command line>:4:23: warning: missing terminating '"' character [-Winvalid-pp-token]
    4 | #define FIRMWARE_DIR \"/usr/lib/firmware\"
      |                       ^

emitting this warning during configure means some tests fail wrongly. e.g.
test for enable -fPIC -DPIC, which results in textrels in libbbluetooth.so

Pass the string definition using single quotes to avoid the shell
"eating" the quotes and other characters

This works well across gcc and clang
